I'm sure you did your research about the Olds 4-bbl manifold, but I know the Oldsmobile 215 was slightly different in the head design. I can't say whether the intake flange was the same or not.

I hadn't looked in quite a while, but just discovered that the SD-455 Registry website is no more. Is there another registry somewhere? Thanks!

It looks like King MB5511XPSTDX are .001" oversized, but they are non-grooved lower and I have a straight-shot oiling crank, so I need fully grooved. Their MB5523 is fully grooved, but not offered in...
