Depends how much space there is which in turn depends on if the heads/block/intake have been milled or not.

You have to mock it up to see and then go from there. I always mill the intake side of my cylinder heads so I can use a double paper gasket but most people don't do that.

To do it correctly the head and the block should be milled so you get a three way match at the top of the valley rail. The cylinder head, deck surface and valley rail should all meet at the same point. Lots of guys never check that which is why they have problems with the intake leaking.

I'm tracking with ya - I'll put the manifold on with no gaskets and see how it all matches up bare - then determine if the paper gaskets are needed. Makes sense with how you explained it, thank you.
