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.
