360 cylinder heads

I have acquired two B300 vans from the early seventies, both equipped with 360s wearing 2bbl carbies.

As the engines are surplus to my needs, and both were non-runners when acquired, I have stripped one down to free the rusted-in piston, clean up and sell. But I don't know about the heads.

Are the heads on these vans the same as those used on cars of the same era?

We're looking at whether or not aftermarket manifolds and headers might fit.

Can anyone help me with this?
