MonteAZBB70 Posted December 28, 2006 Share Posted December 28, 2006 I know this question has been asked lots of times by a lot of different people, but here it goes again. I have a mild 402, column shift TH400 w/ AC. I've been told that full length headers are better than shorties, but I don't want to make any major mods to make them fit - including dimpling so I would consider anything. Has anyone used Doug's Headers or Doug Thorley Headers? They both appear to have nice thick flanges. How about Hedman Elite's? Any recommendations? Thanks!

Ian Posted December 28, 2006 Share Posted December 28, 2006 Try these Patroit Headers at Summit Racing I just put a set on my car and they fit great. Steve had put a set on his too and was the one that showed them to me. They come coated and uncoated. Ian Link to comment Share on other sites More sharing options...
John Burns Posted December 28, 2006 Share Posted December 28, 2006 Gents, I noticed this footnote on the Patriot headers: 54 - Fits manual and automatic transmission floor shifts only. -John Link to comment Share on other sites More sharing options...
Jared Richey Posted December 29, 2006 Share Posted December 29, 2006 I have to been told to use HOOKER SUPER COMP HEADERS with the big tubes. Of course they'll set u back around $400. Very good headers though, this is what I will be putting on my 454 SS. Link to comment Share on other sites More sharing options...
Sam (Bones) Posted December 29, 2006 Share Posted December 29, 2006 hooker SUPER comps do not fit , if you are looking at the 2" tubes for a chevelle, the 2" COMPS fit very well but you need to relocate the proportioning valve, if you call hooker they will tell you they don't make any to fit a monte I learned the hard way with the super comps for a street engine the 1 3/4" tubes would be better, I'd listen to Steve also you may have trouble with any headers because of the colum shifter my 2 cents Link to comment Share on other sites More sharing options...
bills70monte Posted December 29, 2006 Share Posted December 29, 2006 I have the hooker super 2" comp on my monte and on the drivers side they are banged up to make them fit and still they rub against the steering shaft. Good luck. Link to comment Share on other sites More sharing options...
Sam (Bones) Posted December 29, 2006 Share Posted December 29, 2006 how it the heck did you get them to fit? the only way I seen that they would work is to move the engine forward about 4" Link to comment Share on other sites More sharing options...
502ci Posted December 29, 2006 Share Posted December 29, 2006 I tried those super comp`s also (2" primary, 3 1/2" collector) and they would not even clear the the driver side A-arm...I momentarly thought about cutting it (the A-arm that is) then I came to my senses... The passenger side seemed to be okay though. I finally installed hooker competition headers and they fit well (2" primary, 3 1/2" collector). I would suggest a smaller diameter though for a mild street motor...which should have even more clearance. Bill Link to comment Share on other sites More sharing options...

Heckeng Posted December 29, 2006 Share Posted December 29, 2006 That will make all the difference. The part that the headers interfere with for the column shift is the linkage that goes down the steering column and eventually to the tranny. Floor shift allows you to remove all of that linkage. My vote is Hooker comp as well, it's what I have and they've been very nice. Link to comment Share on other sites More sharing options...

Ian Posted December 29, 2006 Share Posted December 29, 2006 Just a note about the ones Steve and I used, I did not have to dimple them at all, and they do not rub anywhere. Ian Link to comment Share on other sites More sharing options...

Sam (Bones) Posted December 29, 2006 Share Posted December 29, 2006 are you keeping the colum shifter? that's the key by what everyone is saying, may have to look for some shorty headers to keep that shifter Link to comment Share on other sites More sharing options...
MonteAZBB70 Posted December 29, 2006 Author Share Posted December 29, 2006 are you keeping the colum shifter? that's the key by what everyone is saying, may have to look for some shorty headers to keep that shifter Yes, I'm keeping the column shifter. I'm not necessarily against shorties, but I've heard that the performance gains would be significantly less than with full-length headers. Is there a big difference with a mild motor?

Sam (Bones) Posted December 29, 2006 Share Posted December 29, 2006 if you were racing, maybe, as for a street ride from the "seat of the pants", I don't think you would notice a difference if you were to hop in two cars, one with long tubes, one with shortys this is only my opinion from my experiences Link to comment Share on other sites More sharing options...
MonteAZBB70 Posted December 29, 2006 Author Share Posted December 29, 2006 Thanks, Sam. Experience is exactly what I am looking for! That should open up the possibilities dramatically. I think I'm leaning toward the Hedman Elites...for now... Mike Link to comment Share on other sites More sharing options...
502ci Posted December 29, 2006 Share Posted December 29, 2006 Another benefit from the shorties is you have the ability to tuck the exhaust up tight as it exits the engine compartment. Long tube headers go all the way down to the collector and then you have to deal with it, this was the limiting factor when I lowered my car...too low and the flange scraped on bumps... As far as noticing it with the seat of the pants on a mild street motor...probably not. But I still think you could measure a difference at the track...maybe a 1/2 a car length to a full car length. Too many variables to accurately say, so that is just a guess... Link to comment Share on other sites More sharing options...
Jared Richey Posted December 29, 2006 Share Posted December 29, 2006 Just another header question for me. Where exactly does the column shift linkage run where the header will come in contact with the linkage. Please clear me up on this. Link to comment Share on other sites More sharing options...

Earlier in this topic it was stated that the big tube headers would get in the way of the linkage. Well that is good to know because I was planning on putting my 454 in the car before I mess with changing it to floorshift. Link to comment Share on other sites More sharing options...
Ian Posted December 30, 2006 Share Posted December 30, 2006 Remember the factory floor shifter and the column shifter both have the same linkage that runs down the firewall to the frame, that could get in the way, but I am not sure why they say only manual or floor shifter, because there is plenty of room around the Patriot headers and the linkage. I will see if I can dig up a picture later. Ian Link to comment Share on other sites More sharing options...
Dans '70 Z20 Posted December 31, 2006 Share Posted December 31, 2006 I am also looking for a set of headers. Probably full length headers with equal length tubes to maximize scavenging. This way each pulse will get to the collector at a different time. Without equal length headers you may have multiple pulses reaching collector at the same time. I just want to note that many of the mass market headers do not look (or mention) that they are equal length. The only ones that do are "Headers by Ed", "Dougs Headers" & "Doug Thorleys". Hedman is coming out in June with a new full length header #66103 coated/ #65103 painted where Monte's are listed as a fit. They have 2" primaries with a 1/4" flange. The Patriot headers Steve used fit perfectly but were a shorty header (clippster), unequal tubes so it did not have all the benefit of a full length header. The did have a 3/8" flange which was nice. Pertronix now owns Dougs headers so if you go to their site you will have access to both brands. Anyone else have any full length headers that fit (other than the Hooker Comps) without the need of any modification? How do you calculate which primary tube size is best for your car? Big block headers run from 1 3/4" up to 2 1/8"? Overkill looks cool but can rob power. Thanks. Trying to gather info because many sites do not even list the monte. If you use a Chevelle header you may be taking a chance. Dan Link to comment Share on other sites More sharing options...

monte70car Posted December 31, 2006 Share Posted December 31, 2006 on my monte i have tuned headers which r full length dont know who made them since they were on the car when i got it in 95. its either the drivers side or the passager side that is about 4" shorter then the other one.
