My last engine started out at 20 and slowly built up to 40 over 20 minutes or so.

My only thought is restrictions of some kind or a bad pump = thick oil not being pumped very well. Lack of restrictions equals the usual cold oil is thicker which gives higher pressure.
Next time you have your oil pan down have a look and a measure of that fitting. On my engine the ID of the ell was significantly smaller than the oil pump discharge channel. I posted the figures here a while back. I'll look for the post.
