I put v11 sport pistons in a California engine. The squish band is/was too narrow on the Sport pistons due to the smaller combustion chamber on the Stock head. I machined the piston dome diameter smaller. I got over 200 psi compression. Lower duration cam and smaller valves are stock. 2003 hydro engine.
How many thousandths did you cut off the dome to fit ?
Thatís good info John. I might have to do a bit better f machining off these pistons.
