I just bought a MS3 finally! after wanting one for about a year now. I have a friend who has a set of stock ls6 heads he says he will port them and sell them to me. We still havnt got around to a price yet. Right now im on a tight budget so cant spend to much. The car is a DD btw.. I want to buy new springs, rods and all before the swap still dont know about heads. Would there be a good gain with a cam only car? Mods in sig. I want this done by spring. Thanks

 

TSP sells their PRC stage 1 LS6 heads for like $950 + $250 for double springs. That's a pretty bad *** deal I think. Good luck with your MS3!
