Couple more oil filter head questions for the Guru's!
From what I can tell, the early oil filter heads, with 1/2" thick flanges, used bypass filtration...meaning only the oil that was bypassed from the pressure valve went through the filter element, and then straight back to the block sump. So, filtered oil NEVER went to the engine bearings.
The newer, 9/16" flange heads appear to work just the opposite...in that all the oil going to the engine went through the filter element, with the exception of the bypassed oil from the regulator.
So, my questions are:
1) Did I get these differences right?
2) Are the engine blocks interchangable, so that either head can be used on any block?
3) Has anyone developed a method of setting the oil pressure regulator adjustment to get it close before installing the head?
