Flat top pistons in a Chevrolet 350 to 414 engine will generally provide compression ratios in the 10.5 to 11.5:1 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 23° aluminum cylinder heads and will normally fit camshafts to well over .600 valve lift.
