Thoughts that the cam bearings were installed wrong blocking passages creating pressure.
any other history of rebuild to change something to create excess pressure?
Engine is out now, but as mentioned, have you tred a different gauge?

And, there’s no need to go to any real trouble with adjustable nuts. A few copper sump drain plug washers under the standard cap (between the cap and the block) will drop the pressure if its too high ... still too high? add a couple more. (If its too low you have another problem).
Cheers, Ian

EDIT: high oil pressure has nothing to do with oil leaks.

The IWIS single chain is supposed to be of good quality or convert/replace the front cover with a later one that has a timing chain tensioner.
I would have tried getting to the bottom of the oil pressure problem by maybe installing an adjustable oil pressure part before pulling the engine.

Driving along with a warm engine the pressure showed 100+. I asked why so high, "shows how healthy the engine is"
