Default #66 heads

I've acquired a 455, it has casting #66 heads. They have press-in rocker studs and bolt-on guide-plates.

My question is:

The pad that the guide-plates set on. Is it the same height as a head that came equipped with screw-in studs from the factory? I'm concerned about clearance between the bottom of stock style rocker arms and the hex on the stud.
