Hey Billy
,
Yeah, you are right about more compression, as long as you have about .040 or more is better. I clayed about .035 pistons and valves (without head gasket on) and am happy with that. Remember that that clearance will change with head gasket added and compressed. My copper head gasket compressed to .050. So, check out what your head gasket will provide when compressed also and add to clay reading.
When pistons 'popup' into a head that allows and still has clearance, that will give more compression. I did not cc my Winfield, as I was only concerned about clearance of valves/piston top. Not much chamber room at all. I'm thinking that the Super Winfield new is 7.5:! . At 4 inch pistons, I'm wondering about sealing between 1and 2 and 3 and 4 holes, so using copper wire.
