[QUOTE="GTSpartan, post: 2177775, member: 21531"] The GTS-R heads I was talking about were the one from when they won LeMans a few years back. I'm not sure if they even make them anymore, but people are copying their design. I think I saw a set for sale a while back for somewhere around 8k. I couldn't believe they can make the viper heads flow 380, but apparently they can and they are on engines that are not for the street. When I first got my heads done and went to the dyno my gains were not as much as I had expected. The tuner reminded me that my blower was no longer pushing 10psi like it was before the head work, but somewhere around 6-7. When I upped the boost back to 10psi then I saw the really big gains.
