It has stock pistons in it with the RC327 cam.

I would seriously question that, short of having the pockets re cut or barrels shimmed up for valve-to-piston clearance...
You say this is in a '77 F?

A black 410 head casting? Without valve interference?
Pics are worth a thousand words, I just can't see how it would fit.
I think you've got a treasure trove on your hands, just not a pure F-2. How did the motor run to this point? That RC327 was one of the baddest of the bad-a$$ed hot rod cams of the day.
