You need to think smal CI so you can get the pushrod out of the port to get 2.2 and up.
I had to design and machine our own cores for my 500" comp engine after some clown here in Detroit moved our lifter bores to a place where no one had cores available. I've been down this road.

you had them moved perpendicular to the deck then? How long ago would this have been?
