Flat top pistons in a 503/514 Ford engine will generally provide compression ratios in the 9.8:1 with an 100cc head range which makes them a good option for engines with aluminum heads and larger than stock camshafts. Valve reliefs are configured to work with most types of standard and aluminum cylinder heads with OEM valve placement and will normally fit camshafts to slightly over .730 valve lift.
