The head will work fine.
You really can't put to big of a cylinder head on it.
To have to big of a cylinder head, you would have to have to big of a cam, to big of a intake manifold, to big exhaust system, ect ect.
And if you had all of that, it would probably run great at max rpm.
The intake and camshaft will determine how much air gets into the cylinder. Yes a larger head will allow more, but only to the point of what restriction the intake and cam provide.

...and an RV cam will not make full use of those heads.

True, but the head will not hurt performance.
