The ports are off from each other as well and the boxes are angled funny. Almost like it slipped in the machine during manufacturing. They are shipping me a replacement. They said it would should be flat. So I'm not sure. They are contacting offenhauser and talking to them as well.

I think the concern you're concerned with is the carb mating surface being parallel with the same plane that the runners share. Use a set of calipers and get specific measurements of the bores to ensure that they're the same. The carb surface is canted on my DP intake as well. For something to shift that much in producing the part, something catastrophic would have to take place. Good eye for detail though....most folks dont notice the slope at all. Its made that way for a reason.

Same here. Both of my 4bbl intakes were sloped like this. And I agree, the engine is installed pointing slightly upward, so the slope is to level the carb back out.

Awesome! Thank you guys for the input. Spoke to Summit racing about the bores and they go ahead and install it if there are any issues they would replace it. They contacted Offenhauser and they stated it would be June before a new one would ever ship.

If you really wanted to be fussy you could overlay a carb gasket for the carb you plan to use and port match the opening to the gasket so no metal protrudes into the path of the bores. That's what I'd do, as long as the studs align.
