B18 head on B20 block 120-130

Hi guys, I've been browsing through the great BrickBoard a bit, but couldn't find what I'm looking for:

I've got a B18A with a nice head, hardened seats and mildly ported exhaust ports, but cilinders are worn, and the engine starts to consume some oil.
I also have a B20 block with rather good pistons but no head.

Can I put the B18A head on the B20 block (using a B20 gasket)? I know it 'fits' but how would such a setup run?

There would be a larger quench area since the actual CC is smaller, but I can't imagine that would be good for flow. Any thoughts, anybody tried?

Thanks in advance, cheers Ben
