NA yes.
It depends on his power levels. On cars making 600 horsepower(with stock valves mind you) there have been major gains from changing heads.
Simple answer to the OP, turn up the boost a couple more PSI. It's not worth it.
I like what your saying lol turn the boost up, I have a full build Gsr all skunk2 parts in the head with the exception of a throttle body and a PnP for whoever said get new valves and build the head, Its already built, i have been told so many times not to waste with changing it because the air is forced in, and i have been told so many times to get it done because it cant hurt it only make it better. Its a little costly to get a good PnP but I am pretty sure i am going to get it done, Just have to save up the money or wait till tax returns. anyways once again thanks for all the great info.
