Any body know the spec for piston to valve clearance?? Mine came out to .105 on the intake, is that too little? Im running stock bottom end, TFS stage 1 cam, 1.6 rockers, edelbrock heads 1.9 valve
A good rule of thumb on stock bottom end 5.0's that are gonna see less than 6500 rpm is .080"-.100" intake and .100"-.125" exhaust.
