SONNY'S 14.5 DEGREE BRODIX PONTIAC HEADS

IN-HOUSE FULLY CNC PORTED, BLENDED & FLOW TESTED.

At Sonny's all head porting is done in-house. We use a state of the art 5 axis CNC vertical machining center.

This unique cylinder head was designed by Sonny's for 500+ cu.in. engines. These cylinder heads are available in 4.840 and 4.900 bore spacing. We offer the heads with ductile seats and replaceable bronze drive-in step guides. These Pontiac castings have incorporated the heart shape combustion chambers and spread port design intake runners.

We have designed a one-piece rocker bar for stability and endurance. SAR can also supply you with custom sheetmetal billet rail valve covers and cast or sheetmetal intakes.
