Hi, It's the second thread I post and I'm a beginner in mechanic so I need some comment on my setup to be sure it ok and all fit together so I have a gm 350 and I plan to buy new cylinder head, intake, rocker arm and I want to know how much HP this will make.

My camshaft spec are this Duration 308/318, Lift .488/.510 do I need to change the cam or with rocker arm with a 1.6 lift It will be ok?
