WIW: Newly Rebuilt 1970 440-6 Engine with 2x3 Factory Carburetors

I am thinking the pad for the engine stampings are not on the same plane as the top of the block where the heads bolt.   

True although sometimes they also need to do the valley pan rails when they deck the block and then if not careful about it the numbers on the pad can get whacked.

None of it makes much difference I don't think for me

Ya can't see the numbers when it's driving down the road.  I'm sure most people will think 'wow, great car' or 'you never see those on the road' or similar.  Your putting a rare/cool car back on the road with your own hands and not just your check book.
