The Brodix ST 5.0 cylinder head was developed for the Ford Windsor engine.

Out of the box, completely assembled ST 5.0 heads produce a 50 horsepower increase over other stock heads, and the combustion chambers may be milled into the mid 50 cc range. All existing stock 5.0 accessories can be used in the installation of the Brodix ST 5.0. The Brodix ST 5.0 R, allows the use of 7/16 Ford roller rockers.

The exhaust ports are raised .500 higher than stock Windsor heads.
