Got around today to checking all of my clearances with with flycuts and piston to head clearance. I had mocked everything up with a used .010 previously crushed with o-rings. For the valve clearances i came up with ~.078 and the piston to head was ~.048. How little is acceptable for a high rpm motor build? I was/still am planning on running a stock headgasket.
Then my other queston, When they rate compression on pistons is there a certain piston to head they go by at all? Would like to get an idea where id be sitting with my 286110's would be with .038 piston to head clearance.
