Hi Geoff,
The usual thing is to have the engine rotated 3-degrees about a point at
the front of the engine. That way the rear of the engine is offset
without being too close to the cowl and the spinner is nearest center of
the cowling's front. Just be sure to know which way the prop goes.
I recently tacked a mount together to find out the owner had a Ross
re-drive and the offset was the wrong way. A days labor lost and a
little tube
to start over but it's done correctly now. Clockwise from the pilot's
seat requires a right offset, etc.
10-degrees here today, but yesterday I flew from 25-degrees on the
ground to a 52-degree temp at 3500 feet in northwest Illinois.

The engine is 3 deg off A/C center line. Does the cowl follow the engine CL to centralize the prop hub within the cowl opening? I imagine it is but I've never thought about it before and I don't recall the subject ever being mentioned anywhere.
