Bloody hell, full of good ideas this evening...

Even easier way of checking and correcting....I'll turn a stainless ring that slips over the protruding stub.

- The ID of the ring will be a clearance fit of the OD of the primary stub.

- The thickness of the ring will be whatever the head step depth is, minus almost the sealing ring thickness (leaving a ittle bit, for nipping-up).

- The wall thickness will be something that allows me to get a file nice and perpendicular to the stub.

And this will very quickly show whether or not the stubs are parallel to the flanges.

And on that last flash of brilliance for the evening, I'm going to bed.
