The LOP guru (Walter Atkinson one of the Advanced Pilot Seminar
people) told me in a post on a Cessna Pilot Association forum that 25
degrees LOP is all you need to do at these power settings with our
O-320. Your 360 shouldn't be very different.

A big part of the "magic" starts to happen as soon as you hit peak
(assuming all cylinders peak together). Anything past that and you are
cooling with air rather than fuel. The reason you hear about running "50
LOP" for example, as opposed to 25 LOP or 1 LOP is to keep temperatures
down at high power settings. It lower power, if 25 LOP keeps your temps
within limits, then great...
