Prebore and floating reamer holder

Tilt on the long axis of the bed probably doesn't matter if both ways tilt the same. It's much easier to just set it up flat on both so you know they match.

For the other Axis I'll go with the manufacturer's specs.

Flat/to spec is also good because if they designed it right, the coolant pan will drain properly when everything is flat/to spec and all of the other tooling should work in that condition.

What you don't want is a twisted bed.

whats your method of finding the bed twist? I know how to fix it but dont have a reliable way of detecting it

I do not have a twisted bed, but other than coolant drainage it matters not on the other planes mentioned. As you probably know a "shift" pot of them were installed on Navy ships. Monarch 10ee was their choice, heavy and the best and most precise made.
Kinda hard to level a ship.

Dusty, put your level front to back on the lathe both in front of the headstock and at the far right. If they read different, you will have twist.
