Safe Valve Pocket Depth

Measure how much piston to valve clearance you have now.

You need piston to head clearance plus .010 for the intake valve and intake valve clearance times 1.6-2.0 and send it.

So, if you have .040 piston to head clearance you need .050 intake piston to valve clearance.

For the exhaust you need that .050 (intake P/V) times 1.6-2.0 which would be .080-.100 exhaust P/V.

Any more than that and you are pissing away compression ratio.

Checking springs should be here tonight, but I haven’t ordered pushrods yet. Once there are here, can I mock up without gaskets at measure valve drop at 10 BTDC and 10 ATDC and add the compressed gasket thickness? I don’t have any compressed gaskets and I don’t want to booger those cometics at $90 a pop.
