Here's 2 pics of a car show; I think it was a 371 and he made a pair of adapter plates to run the earlier 303 intake. I sort of recall 16 on the head? not sure.

Your gasket shape is correct for Olds.

No idea on value, things have changed since I got off ebay 2 years ago.

 

Oldsmobile looks correct. The price is going to vary on condition and how bad you want them.

 

I vote early Olds,
yes you can still buy them new . I'd give ya $20 ; p
I'd say $100 to $150 depending on what new ones cost . figure half to 3/4 of new price , new ones will be polished too
