Fully Race Prepared CNC Ported Castings
(Picture may show optional equipment. Click to enlarge.)


At SAR 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.

The BB-5 heads are the largest intake port BBC head castings, with raised port aluminum cylinder heads recommended for 565 cu. in. and larger engines, with capabilities of sustaining 600 + cu. in. Other features include replaceable step bronze guides, 2.350" x 1.900". Custom Sonny's heart shape chamber design is also incorporated in this cylinder head.
