It's a heavy duty Berg pump, but no doubt it will be working much harder
pushing that oil through the full-flow, hoses and cooler. Should I just
replace the pump every 20-30K miles or so to be on the safe
side?

Re. hot idle and fwy oil pressure, I don't have a gauge, so no clue.
Where would the sender for a pressure gauge mount?

My oil temp sender is at the oil relief so it is definitely registering
the temp at the hottest point. (I calibrated the gauge with the high-tech
boiling water technique, using both Meat and Candy thermometers... it was
within 2 deg.). So witht he cooler/fan setup the oil temperature problem
is solved for now (or compensated for) but I am still on the hunt for
anything else that could possibly be causing that extra heat. My cool air
system is tight down to the bung... absolutely no holes/leaks/missing
tins/blockages. Advance set to max at 30 deg on the new 009, compression
normal, 170 mains were selected on the dyno, and look OK on visual
inspection. Everything is tight, and it runs very strong and sounds great
(vapor lock problem when restarting hot aside!) so I'm stumped aside from
the possibility that it's just due to the larger engine size. 

As always thanks for the response(s)!
