Trimmed the two oil cooler aft side support brackets to let a little more air through. After constructing a pretty involved baffles and obviously trading airflow through the cooler vs. airflow through the heads (as it all goes out the same exits), I trimmed probably 2 in^2 of material off those brackets to get a hair more cooling area working. Also soaked the cooler in/out fittings in mineral spirits to clean them up for when a repaired or replacement cooler arrives.
