>I am trying to locate a pressure
diagram, or at least some solid discussions about where high and low
pressure is on a 360 cowl.<

You might also want to consider that cooling will be most critical when
flying at high angles of attack during climb and in the pattern at lower
IAS.  In an old issue of the LNN, there were a few pictures of tuffed cowls
that might help.  Don't recall which issue though. I would guess that the
intake should be towards the lower front of the cowl and the exhaust at the
upper aft optimally which would insure maximum cooling at high AOAs.

I had oil temperature problems too which were solved by reshaping the
plenum behind the intake NACA scoop.
