Dome top pistons in a 412 Cleveland Ford engine will generally provide compression ratios in the 13.0:1 range which makes them a good option for competition engines with aluminum heads and larger than stock camshafts. Valve reliefs are configured to work with most types of standard and aluminum cylinder heads and will normally fit camshafts to slightly over .750 valve lift.
