I learned to get the feel with a feeler blade, that checked correctly with my “P&G Valve Gapper. Ran no faster, showed no better on the dyno using it, than the “feeler blade” after learning that. Seems many set them too tight with feeler blades. If you found what lash runs quickest with feeler blades, there is no power to be gained, in my limited experience, using the P&G. If they are even still made & sold. Worked with mine about 1970. I don’t think I know everything, just sharing what I experienced.
