Twisted Wedge Valve Reliefs


Flat top pistons in a Ford 351 to 454 engine will generally provide compression ratios in the 10.5:1 to 14.0:1 depending on engine size and cylinder head range which makes them a good option for engines with competition applications. 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. Some are available with a dual intake valve relief for use with standard as well as Twisted Wedge or TFS High Port cylinder heads.

Please select your piston from the list below, or select from the categories listed above.
