That's 380F on Cyl 2 which is now my hot cylinder.
I first sealed up everything I could with hi temp silicone. The baffle holes for the engine mount bolts are sealed with cups (big gaps there).
Then, noticing that Cylinder 1 and 2 were my hot cylinders, I cut down the dams at the air intakes. An improvement was noted but #1 was still hottest so I removed the entire dam. Now #2 is the hottest so I'm going to completely remove that dam as well (as others have suggested). If everything else stays the same, I'll be running 365 to 376 during the climb. It may be hotter in summer - these temps were seen on a 55F day.
I wish my oil access door didn't leak so much cooling air.
