true blue Posted January 20, 2008 Share Posted January 20, 2008 Just wondering if these will fit or if someone can recomend the best fit, ceramic coated or stainless that will hold up good. 454 BB of course. http://store.summitracing.com/partdetail.asp?autofilter=1&part=HOK%2D2455%2D1HKR&N=700+4294908216+4294908176+4294925080+4294840133+4294923429+4294839039+115&autoview=sku Thanks TB Link to comment Share on other sites More sharing options...
502ci Posted January 20, 2008 Share Posted January 20, 2008 Those are the exact ones I have on my 502 motor. One thing, they will hang low under the car as most "long tubes" do. Link to comment Share on other sites More sharing options...
Ian Posted January 20, 2008 Share Posted January 20, 2008 Bill I was looking at your site for a side picture to see how low they hang and could not find one Do you have one that shows exactly how low they hang? Ian Link to comment Share on other sites More sharing options...
Sam (Bones) Posted January 20, 2008 Share Posted January 20, 2008 I have the same ones too as Bill said before, you will have to relocate your proportioning valve Link to comment Share on other sites More sharing options...
502ci Posted January 20, 2008 Share Posted January 20, 2008 Here's a view of them...you can see at the collector is where I have a collector extension that starts to angle the exhaust back up. The funny thing sticking out at an angle in that extension is a y-pipe cut-out. Bill Link to comment Share on other sites More sharing options...

TN454Monte Posted January 20, 2008 Share Posted January 20, 2008 Bill, If I may ask what is that paint code on your car, or is it custom? Is that a GM color? Reason I'm asking is I had a 73' years ago (my first car) that was Burgandy and it was pretty darn close to that...if I don't keep mine black I want to go with either that sort of color or the Dark Cherry Metallic from a 1995-96 Impala SS.

502ci Posted January 21, 2008 Share Posted January 21, 2008 Bill, If I may ask what is that paint code on your car, or is it custom? Is that a GM color? It is a GM color...but my car no longer looks like that, picture was taken about 5 years ago and the photo was color enhanced...although that is how it looked back in 1983 when my Dad painted it. We went from car dealer to car dealer looking for a color and when we found it we got the paint code off the dealer...it was so long ago I don't remember the code...sorry.

Dans '70 Z20 Posted January 21, 2008 Share Posted January 21, 2008 TB, Based on my findings. *Hookers will fit but may need to move proportioning valve (very close) and some have mentioned slight ding needed in one tube. *Doug's headers pride themselves on fit. They say they have one to fit our application. Very good quality and I believe now owned by Pertronix. *Sanderson Headers have a full length and a block hugger for our application. Held up my BB3 Blockhuggers 1 7/8" tubes to a friends 454 and fit looks beautiful. If their full length fits as well it is a nice option. My block huggers end just past fire wall and have an elbow attachment at collector to keep exhaust as tight to floor pan as a stock system. *Patriot and Hedman shorties work really well but have a smaller tube diameter Dan Link to comment Share on other sites More sharing options...
TN454Monte Posted January 21, 2008 Share Posted January 21, 2008 Thanks Bill..I'll dig around and see if I can find that paint code. Dan says...*Patriot and Hedman shorties work really well but have a smaller tube diameter Here's a good look at a set of Hedman Ceramic Shorties installed on my 454 in my '72...

Sam (Bones) Posted January 22, 2008 Share Posted January 22, 2008 depending on how the engine is built, the smaller tubes may be better Link to comment Share on other sites More sharing options...
Guest Evil Austin Posted January 22, 2008 Share Posted January 22, 2008 Doug's header looks quality, how close is it to the brake proportion valve ? -EA Link to comment Share on other sites More sharing options...
680HPStroker Posted January 22, 2008 Share Posted January 22, 2008 No one and I mean no one has an application specific header for a FGMC. The above mentioned headers fit good. I have them on my 454/489 engine, but you will need to move your brake proportioning valve and a lot of people have to dimple one, or two primary tubes to clear the steering shaft. No two FGMC's are exactly alike. If you buy these and they don't clear your steering shaft you just wasted the money spent on the ceramic coat. Buy the same headers, but uncoated. Test fit them, make any necessary mods to them, and then send them off to be ceramic coated. Better to be safe than sorry. Also don't try the collapse the primary tube to clear your brake proportioner trick as it's ugly, burns up the valve, and restricts exhaust gas flow. Some idiot did that to my first set. Lost a customer for life and he was (did I mention was) one of the top speed shops in my area. Now because of this type of back alley work the guy is going out of business. He screwed a lot of people. Link to comment Share on other sites More sharing options...

Knightrider Posted January 24, 2008 Share Posted January 24, 2008 Got the Hedmans on mine, Perfect fit, easy to work on and around, no repositioning of anything. Link to comment Share on other sites More sharing options...

Knightrider Posted January 24, 2008 Share Posted January 24, 2008 Yes, its a big block. Found them (I think, don't have the car in front of me at the moment) http://store.summitracing.com/partdetail.asp?autofilter=1&part=HED%2D66002&N=700+400143+300691+4294908216+4294840133+115&autoview=sku Had a few gasket issues at first, blew them out twice, then switched to copper, no problems since.

Knightrider Posted January 25, 2008 Share Posted January 25, 2008 Sorry, those aren't the right ones, Ill keep trying to find them, they are shorter and the collector area doesn't flatten out like those ones. Link to comment Share on other sites More sharing options...

MonteAZBB70 Posted January 25, 2008 Share Posted January 25, 2008 I wish they made the Elite series in a longtube for a BB Monte. I've never had good luck with headers and the idea of a 3/8" thick flange is very appealing to me. I know Doug Thorley does, but I don't know of anyone here who's used them and I just can't see shelling out that kind of money right now to find out how well they fit. I'll just stick with manifolds for now I guess. Thanks. Mike Link to comment Share on other sites More sharing options...
502ci Posted January 25, 2008 Share Posted January 25, 2008 Besides the fact that they are shorties, this would stop me. "Not recommended for use with aluminum heads." I noticed that also but I think they were possibly referring to this statement of theirs..."208 - Chevy 502 big block generation 6 engines with aluminum cylinder heads will have clearance problems on some applications. Bottom of header flanges may hit head bolts. Notching may be necessary." Bill Link to comment Share on other sites More sharing options...

502ci Posted January 25, 2008 Share Posted January 25, 2008 I had to do that to my hookers I had to do alot of grinding on my Hookers... Their flange is so big and thick though I had no worry I was gonna take too much off...and I never had a leak, so all is well... Bill Link to comment Share on other sites More sharing options...
