The only three bolts that actually lineup are the two lower intermediate plate bolts and the top left at the outer edge of the cylinder Bank. None of the rest lineup including all of the pan flange on the alloy block pan. I'd say the top right Bank hole could be drilled and tapped but it's not going to help with accurate alignment. The iron block does indeed have two dowel pins in the block directly above the two bottom outer bolt holes. The alloy block has such a more substantial rear main seal cover plate that there's no way you could get enough carved out to fit over it I don't think. No top. Bolts

So the dowel pins do nothing for this plate, and simply hoping that the bolt holes line up the plate is a bad idea.

Do I understand correctly?

Or is the plate obviously off center when using the bolt holes?
