This next winter i will be on a budget engine rebuild and the heads seem to give me to most problems. Sure for 1000 bucks i can get a nice set of aluminum cylinder heads but i was wondering about these. for $697 (if they are assembled) sounds like a hell of a deal in the 58cc. The rest of my combo will a Trick Flow Track Heat intake, FTI cam, long tubes, 65mm TB, MAF, CAI, American Thunder catback, 4:10 gears and a built c4 with stall. If assembled, do these sound like nice heads considering they are only a few hundred more than say GT-40Ps?
budget heads?

tmoss definetly knows a lot about flow numbers, but i think the person you really want to talk to about heads, no offense tom, would be thumper460. try to keep this thread alive long enough for him to see it...or shoot him a

I think the flow numbers are great for the price - but I want to see them translate into the same potential power on a dyno or the track. We do have some guinea pig (correct speeling) volunteers don't we.
