gprimm Posted March 28, 2012 Share Posted March 28, 2012 Having to upgrade the heads on my GM 350/290hp crate engine. The one from the factory smoked and when looked at it, the valve seals were coming apart. Nice. This will never be a race car. Has a Comp Cams XE268 cam. Was considering the Edelbrock E Street cylinder heads ($909) at Summit. Also saw the Brodix for $190 more. Leaning toward the Edelbrock. Opinions welcome. Ordering on soon so I have them for the weekend, or Spring Break next week. Quote Link to comment Share on other sites More sharing options...
Andy's Auto Posted March 28, 2012 Share Posted March 28, 2012 Best bang for the buck are GM L31 heads. They used them on 350 "R" engines from 96 all the way up to 1 ton trucks in 2003. You heed self aligning rockers and a specialized Eddy intake for the app, but these things make POWA!!! Quote Link to comment Share on other sites More sharing options...
gprimm Posted March 28, 2012 Author Share Posted March 28, 2012 the 290/350 is a Gen 1 crate motor. Can I use the L31 heads on the old school block? Quote Link to comment Share on other sites More sharing options...
Andy's Auto Posted March 29, 2012 Share Posted March 29, 2012 Yup, no mods needed to mount them on an old school Quote Link to comment Share on other sites More sharing options...
gprimm Posted March 29, 2012 Author Share Posted March 29, 2012 Vortecs, ok. After considering this I am going with the Edelbrock RPM, 64cc. I can use my intake. A local shop will sell them new for $485 each, hard to beat that. Beat Summit & Jegs price by $70, even after tax. Nice. Quote Link to comment Share on other sites More sharing options...
Blue502 Posted April 2, 2012 Share Posted April 2, 2012 That motor is just crying for a cam!With those heads and a cam it will make a big difference. Quote Link to comment Share on other sites More sharing options...
