Flat Top
Flat top pistons in a Ford 351 to 408 Cleveland engine will generally provide compression ratios in the 9.0 to 10.5:1 range which makes them a good option for engines with iron or 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 well over .600 valve lift.
Dish Top
Dish top pistons in a Ford 351 to 408 Cleveland engine will generally provide compression ratios in the 9.0 to 10.0:1 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 and will normally fit camshafts to well over .600 valve lift.
Dome Top
Dome top pistons in a Ford 351 to 428 Cleveland engine will generally provide compression ratios in the 13.0:1 range which makes them a good option for competition engines. Valve reliefs are configured to work with most types of standard and aluminum cylinder heads and will normally fit camshafts to well over .600 valve lift.
