Without knowing who and how the motor was rebuilt there are alot of questions. If the oil passages were not cleaned out after the hottanking and all machine work being done. There could be something plugging that oil passage. If all the oil passages were cleaned real well and the motor built well, then I would look at adding oil restrictors in the heads to keep more oil in the mains and cam bearing areas.

You mean the cam bearing positon in the block where the oil passage comes down to oil the main bearing?
