well the best way is to put clay on the piston and rotate the motor and check the clearance.u want .100 min clearance...one thing tho is that to big of a cam aint gonna help you..plus with the stock heads they dont breath for shit so if u get a big cam that will make it breathe ur stock top end wont breath.basically u have to match everything.if its stock id just get a f cam or something cheep
