SONNY'S 14.5 DEGREE BRODIX PONTIAC HEADS FOR MARINE APPLICATIONS

At Sonny's all head porting is done in-house. We use a state of the art 5 axis CNC vertical machining center, which can produce precision work to programmed "blue print" specs. 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 these heads with Ductile seats and Ampco 45 replaceable drive-in step guides. These Pontiac castings incorporate the heart shape combustion chambers and spread port design intake runners. We have designed a one-piece rocker bar for stability and endurance. SAR will also supply you with custom sheet metal billet rail valve covers and cast or sheet metal intakes.
