Re: revised pro comp heads?????

got them from skip white on e-bay, $ 479.00 for the pair will post performance asap......keep in mind this is a street/strip car, so with some tuning were hoping to hit high 7s 1/8 mile.
Re: revised pro comp heads?????
Wow$479.00 a pair I am assuming that was the bare price for aluminum heads?

Re: revised pro comp heads?????
we used the bare heads because i wanted to touch up the ports as mentioned. i also had spare competition products stainless undercut valves to fit as well as 600 lift springs, 10 degree retainers and locks. so if you feel that you can run them as is for $649.00.....thats ok, but check out what quality parts are being used. i prefer to do my own assembly and clean-up, and port matching. if you decide to go the flat tappet cam route , i would use shell rotella 15-40 and run a container of gm oil supplement seems to allow the cam to live longer life, and other engine parts seem to wear less.......just my experience and 2 cents.....
