The problem I see you possibly having will be with the exhaust manifolds and dipstick. The 305 heads use a different bolt pattern some or maybe all of the time. You know how a couple of the exhaust manifold gaskets in the set always have a space for two different bolt holes? That's the issue. The spacing is different.
Look at the double bolt holes on the number 8 cylinder in the photo below. It is drilled for both.

Your best solution, IMO, is to use the exhaust manifolds from the '85 305 so that you won't have manifold or dipstick issues. I assume headers would avoid the whole issue, but I don't know for sure. I don't own anything with headers, and never have.

I will definitely be checking this out when both engines are out, they do have different manifolds now but I'm not sure about the holes in the heads, and with different manifolds I assume that requires a different dipstick? I was hoping to use the current truck manifolds that go downwards just so the exhaust would bolt up, but If I have to use the upward ones I'm sure I've got enough exhaust pipe between both vehicles that I can rig something up that will work.
