Dish top pistons in a Chevrolet 400 to 434 engine will generally provide compression ratios in the 9.5 to 10.5:1 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 23° cylinder heads and will normally fit camshafts to well over .600 valve lift.
