Has this lower intake been milled?

[projectPONY]

Wondering if someone has a lower Victor EFI laying around that I can compare mine to? Or can someone tell by looking at it?

That texture looks a lot like someone cleaned it with a scotch brite pad

nah, what I see is more of a circular pattern. something like a mill would have left.

looks exactly like what a roloc bristle disc leaves behind, i've done plenty of intakes and they look just like that

How do you explain the mating surface being almost at the level of the lower plenum?

I'm not saying it hasn't been milled but I am saying that the surface in the first pic looks identical to getting cleaned up with a disc. I am absolutely sure those are not milling marks in the first pic, they are way too inconstant.
This stock photo tells me that it has been milled.

Damn! It definitely looks like it has compared to that pic. Now, pardon my ignorance, but why would it need milling on the mating surface?

Decked block, milled heads, lower the intake to line up the ports.

I would test fit it on the motor to see how it lines up with the intake ports

I'll do that tomorrow. Thnx
