Flat top pistons in a Chrysler Late Model Hemi engine will generally provide compression ratios in the 9.0 to 10.5:1 range which makes them a good option for boosted 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 .600 valve lift.
