Dome top pistons in a Chevrolet 350 to 414 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 23° cylinder heads and will normally fit camshafts to well over .600 valve lift.
