Flat top pistons in a 438ci Ford Windsor will generally provide compression ratios in the 12.5:1 (61cc head) range which makes them a good option for competition engines with aluminum heads and larger than stock camshafts. They also work well in heads with larger combustion chambers. Valve reliefs are configured to work with most types of standard and aluminum cylinder heads and will normally fit camshafts to slightly over .600 valve lift. Alternative compression ratios are available on request.
