Its in the sticky. Mamo suggested doesn't suggest that you do much accept upgrade to their valve springs, use 62cc combustion chamber (raise compression), and have him port your IM. Pretty solid combo if you ask me. My car dynoed 436 before the tune... Of course then it spun a bearing, but that ain't the heads fault. With that cam, you should be well into the 460s I would think, but then again these cars respond differently so who knows.

Nothing, that is the best thing to do. Just run the right springs and mill the right amount with comfy PTV.
The best you can do to this combo is degree the cam, run thinner gasket for better quench (do that before mill so you don't mill too much) and spend a good amount of time tuning.

Best advice for those AFR heads, perfect out of the box...

I agree. AFR spent lotsa R@D $$ to make these perfect out of the box. Messing with them will only hurt.
