B and 3B head question

[Radd Cruisers]

Do they interchange and if so are there any difference between the two?

Thanks Wayne, your right about the studs, I checked with a 3B manifold.

If it fits the 3B I see not problem, the studs could be removed redrilled and tapped for larger or maybe they make a step stud??

or use a tappered washer to center the manifold to the studs...

What is the difference between the B and 3B? Does the B have smaller/bigger valves? Port sizes?

Not a 100percent but I think the heads are identical short of the studs.
