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
