Hi Bob
Well it's not the rocker arm assembly spent an hour this morning testing the theory that it was excessive flow from the individual rocker arms that was causing the low oil flow from the rocker arm bypass or over flow.
After bring the engine up to temperature and basically stabilize at 1500 RPM here are the results the end result was with the oil line to the rocker assembly disconnected and blocked there was no difference in oil pressure. Also posted a really dull video

So spent the rest of the day working on reassembly of the HUP pretty much decided that I'm going to concentrate on getting the HUP completely reassembled. Tomorrow I plan to bring the other 216 engine down from the loft and set it up to run. That way I'll should be able to get the HUP on the road for the 25 Anniversary Weare Rally end of July.
Should take me about 3 hours to set the other engine up and test it. I'll come back to this engine once everything else is done.
Cheers Phil
