Intake manifold pulling oil

I will check tomorrow to see what year the block is, can’t remember off the top of my head

Intake isn’t bottoming out on China walls I did verify that. Even without gaskets it is close but when gaskets are on there is about an 1/8” gap after it’s torqued down

I did see the other day that the heads are on different sides than they came off of before head work was done and I wondered if that could be an issue. I checked angles again and one side is 132.1 degrees and the other side is 131.7 degrees so I didn’t think that was enough to throw it off but what do you guys think?
