Greetings!

I am trying to decide the best route to go for my setup and I would really appreciate any advice anyone has!

I have an 04 gto(LS1), M6, 3.91, LT, corsa, 100-150 shot, CAI. I have just got some ls6 heads from a 05 gto and looking at a cam/spring kit and minor head porting, and possibly rockers if you think they are worth it.

I have head a lot of good things about the HPE S-cam(238/242 608/612 115LSA) but I am curious if there is a better cam for N20 and stock or minor ported ls6 heads.

Any suggestions about what cam or who could port heads cheap in tx?

Thanks!!
Walt
