My 422 smallblock build
One other thing I ran into with this block is when I drilled out the passenger side oil galley that also enlarged the hole in the front face of the block. The factory size oil galley plug (19/32) that comes in the kit was now to small. I measured the hole with calipers best I could and ordered up a 16.5mm plug. It fits but it could be just a hair tighter, maybe 17mm or equivalent would be better.
@pittsburghracer , do you run into this scenario when you tube a block?
