PISTON TO VALVE CLEARANCE

[NRM90GT]

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.

When you measured did you take precautions to be sure the lifter plunger wasn't depressed? If you used clay, and it was -- then you'd have to subtract the plunger depression dimension from your number -- which would likely put you under the minimum...
