Flat top pistons in a Big Block Chrysler engine will generally provide compression ratios in the 10.0 to 11.0:1 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 .650 valve lift.
