I was wondering what would make more power a P&P gsr head with type r cams and skunk2 manifold or a stock type r head on my gsr. And about how much Hp to the wheels will i be making with each one

 

P and P GSR head is better than a stock ITR head
i would get hi compression pistons and since u got the head off too
dont know if ur gonna upgrade the valvetrain, u can keep it stock if u dont move ur redline up
get a hi flow header and vtec controller and you will be flyin
