Dished top pistons for the Chevrolet 502 Big Block

Dish top pistons in a Chevrolet 502 engine will generally provide compression ratios in the 8.0 to 9.0:1 range which makes them a good option for boosted engines with larger than stock camshafts. Valve reliefs are configured to work with most types of head with standard valve locations and will normally fit camshafts to well over .700 valve lift.
