Resurfacing deck, affect on cylinder bores

I take it that it was progressive, for example: .000, .004, .008, .012 difference front to rear and the same rod/piston combo showed no taper on the opposite bank.
As far as an engine block geometric tolerancing, the deck parallelism is called off the crank centerline, not the rod journals which are eccentric.
Both banks would need to be decked and the intake manifold milled as well. Whether decking a block or milling heads, I think the formula was .0095 off the intake per .010 removed from the headgasket surface for a LA engine.
