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.
