I hate when people say that, its not true.

GSR head is a better STREET head with more midrange TQ cause of the manifold. Now if your talking about runnink a skunk2 manifold to eliminate the butterflies, i still like the GSR head cause you get the added compression from the quench pads in the head.

ANother good thing about the GSR head is that the quench pads also move the flame into the center of the combustion chamber for a more even burn.

This is not to say that the B16 head sucks, cause im running one on my new motor cause i need to keep my compression down (12:1 already), good things about the B16 head is that you can run a AEBS intake manifold (not available for the GSR yet) which is the best manifold on the market.
