The vertical height increase would be .527" also. As you know this would vary slightly due to stackup of tolerances/head/deck milling/head gasket thickness but this number would put you pretty close to the change you would need to allow for for ex pipe changes etc live every 24 hour block of time like it's your last day on earth

The farther from the deck you get, the bigger the difference becomes. So you were likely close at the deck height. But 5-10" higher at the top of the valve cover would be way different.

Dead on exactly, the bore centerlines on each bank at the deck would have been 1.05 wider & further up the V the ex manifold bolt holes which is what the OP was asking about would be even farther apart than that. live every 24 hour block of time like it's your last day on earth
