Im installing both this spring. The cam is an FMS 226/226 .594/.594..114lsa. It is a custom grind. Also Mac headers with an ORY..And 918's of course.

Default

See my sig for before and after results...I had more boltons with cam and headers, but in your case you can expect 40-50 rwhp on MAC headers and F4 cam..
