The compression ratio is 9.5 .
I want clearance between cylinder and piston ( some person say 0.008 ) , I don't know what is the correct and the best , ( the boost mybe 12 psi or more >> )

the pistons specs is ( piston volume is -7cc , piston bore is 4.030 )
the cylinder heads is ( 71.06 cc )

thanks
