Listen! I don't mean to put all of your methods down. But times have changed. I can remember not that long ago my telephone had a wire going to it.
It took a long time to get our machines that we have. They are for us and racers we know and meet. My son charges $200 to square deck a V8. Break a tool and there goes a couple hundred
He was telling us tonight the proper way to machine a new block is
1. hold the block and Bore the cam tunnel
2 hold the block by the cam tunnel with a cam bar and cut the mains
3 hold the block in the fixture by the main bearing bores and set the deck height on one side by using the Cam and crank center which is 45 degrees to the first deck. Zero the DRO
4.Turn the fixture and it will go past center to 45 degrees to the other side of the center this will be 90 degrees from the first deck This is square decking. Exact 90 Degree head surface difference is squaring the decks. If you cut to zero on the second Deck they will be the exact same height and 90 degrees apart. Another words a framing square will set from deck to deck. Square!
What I did but I did the crank line bore first- wonder what the difference is
as most of us know one cam bearing is usually tight on a BBM
