Flat top pistons in a 347 Ford 4.125 bore engine will generally provide compression ratios in the 10.2:1 range which makes them a good option for engines with cast iron heads with at least 68ccs, as well as any engine with aluminum heads. They are boost and Nitrous friendly and have valve reliefs configured to work with most types of standard and aluminum cylinder heads and will normally fit camshafts to slightly over .600 valve lift.
