you can use straight lifters but the offsets clean up the pushrod angle some. Here is a pic:

When using the offset lifters you may have to clearence the 4 casting lugs in the lifter valley near the block deck for pushrod clearence.
On a 400 low deck with Indy 440-1 offset intake rockers, this is what it looks like.

My 440-1 heads on the low deck with non offset solid roller lifters didn't rub on the low deck block
Yes, we have been saying combining a low deck, 440-1 (or B1) offset rockers, and offset roller lifters. You didn't have all of them.

Sometimes you get lucky and sometimes you don't I did notice on the 440 block that the 7/16 pushrods are very close to the block lugs. I forgot to mention, I think, that the low deck motor had 3/8 pushrods and the 440 motor has 7/16

Those pictures are good. So .485 lobe lift with your cams base circle and a bushed aluminum World block look fine with the IMM roller lifters. I think those are a great design. It looks like the top of the lifter is below the top of the lifter bore at zero lift. And the lifter sticks out roughly 3/8" at max lift.
