is there a good site that will tell me what the cc's are to certian heads? and what the heads are. i know Wallace has some of that, but like on 4x's and 6x's? we have a whole car full of pontiac heads that we have been hording of the years. and i'm trying to find out a set of good heads to run a everyday driver, and another set for a all out drag car.i was digging around and found some 46's 7k3?'s a bunch of 6x's and 4x's 670's and a bunch others i don't remember. i know the 46's came off of a 350 GTO, and i'm not sure that the guy who has been hording them for years will let them go. so is it hit or miss on the 4x's and 6x's? i can look at the combustion chambers and tell on some of them. i know the 670's are to high compression for anything i want to do for a steet car. the all out drag car might end up being a turbo motor so i don't think they would work on it. can you tell by the casting #'s what the heads are with the 4x and 6x's? or is there a big fat book of casting #'s? suck if they where dang old chebby heads i have a book that tells eveything! i need one that tells me pontiac heads!
thanks guys
