These 2 Piece Billet Aluminum Heads are built in-house here at Sonny's. 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 water jacketed cylinder head was designed by Sonny's for 500 + cu. in. engines. The intake runners are symmetrical and feature all good runners (runners that direct towards the middle of the cylinder). We offer the heads with Ductile seats and Ampco 45 replaceable drive-in step guides.
These cylinder heads are to accommodate 5.000" bore center applications, like IHRA Pro-Stock and Pro-Mod, Pro-Street cars, Tractor and Truck pullers, and Unlimited Marine/Boat engines.These heads work great for turbo and blown applications as well. Blocks and cranks can be purchased from Sonny's to match-up with this ultimate performance cylinder head.
