Flat top pistons in a 511 inch Chevrolet engine will generally provide compression ratios in the 9.25:1 range which makes them a good option for Screw Blown engines where limited mechanical pressure is desired. Valve reliefs are configured to work with most types of standard and aluminum cylinder heads and will normally fit camshafts to over .750 valve lift.
