Trouble with cylinder head clearing the alternator

Guys,
I’m finishing up the assembly of my Pontiac 400 build and I’m running into clearance issues with the alternator and the heads. It’s a factory alternator and KRE DPort heads. My disassembly photos don’t indicate I’m missing a spacer or anything but the back of the alternator is hitting the head. Am I missing something here? Is it possible the heads are so much bigger that they’re causing clearance issues? Please see the attached photos and thanks for your help.
Mike

that uses the tube bracket that bolts on to that b oss

and the clocking of the 2 halves looks 90 degrees off

Yes agree, it may fit if it is reclocked. But you want the correct alternator, spaced right to line up the belts,...or they will squeal.
