and this page shows good comparisons of Ford engines, I wish they said MM specifically, so we could know once and for all what exactly is in this engine...

The Navigator heads ports are too big for a naturally aspirated 4.6L street car but may make for some impressive horsepower on forced induction cars.
and
The best heads offered to date have never been installed on a production vehicle. These are available on the FR500 crate engine. The heads on the FR500 are available from FRPP under part #'s M-6049-T46 and M-6050-T46. These heads are bare, but FRPP does sell a hi-lift (12mm) camshaft kit that includes cams, valves, springs, retainers, and rockers under part # M-6550-T46. The heads sell for about xxx.00 each and the cam kit is xxxx.00

there is some good reading on this link - i feel smarter already
