Ford 4.6L SOHC 16 valve / DOHC 32 valve



Our 32 valve heads are in the process of being dyno tested. As soon as we have some info we will finish this page. For now I can tell you this head produced killer numbers on the flow bench in stock form and it responded very well to being ported, flowing nearly 300 cfm at .500 lift! We're expecting some big horse power numbers. The test car is a 1996 Mustang Cobra and progress can be tracked at either Krazy Koncepts or at Speed Addiction. The previous combination with stock, non-ported heads made 640rwhp / 733rwtq as can be seen in the videos below.

Check back soon!
