Re: Valve Clearance Question>>>?? (1 2 NV)
I agree that clay sucks for checking valve to piston clearances. I personally use light valve springs to do that job. There is however one clearance check where clay is indispensible, that is checking the radial clearance between the valve head, and the relief pocket. I have seen many instances where either the reliefs were undersized for the valve, or just not located correctly. Keep in mind that removing material from the head or deck not only brings the bottom of the valve closer to the top of the piston, but also brings the edge of the valve closer to the back of the relief.
