Flat top pistons in a 380 inch Chevrolet engine will generally provide compression ratios in the 10.75:1 range which makes them a good option for engines with aluminum heads where the use of pump gas is desired. Valve reliefs are configured to work with most types of standard and aluminum cylinder heads and will normally fit camshafts to over .650 valve lift.
