After the coolers, the air exited from the two openings on each side of the prop hub. Air coming out of the coolers is always cooler than the engine block, plus, expanding air cools somewhat.

What provision did/do you have for the exiting air from the engine cowl area
once it has gone through the coolers. I have some pictures of your cowl, but
it's hard to tell where you have the exiting air routed.
Does any one use a exit duct to contain the hot air coming off off of the
radiator and oil coolers? I know this would take an excess amount of space,
but would help keep under cowl temps down.
