No, they're left open. At the time I didn't realize one is supposed to install bulkheads there. All I have is a strip of 1.5" wide .040 alu lying flat following the cowl curve around. Stabilizes the cowl exits a bit.
You have the fiberglass extensions? Want to sell them cheap?
FWIW, the CAFE Foundation's research has shown that using a cooling exit shape very similar to Finn's cheek exits might be the most efficient way to get air out of the cowl.

Interesting, but what about cooling drag? Right now I have way more cooling than I need. I was hoping to reduce cooling drag by closing off those exits - potentially with the few inches of the cone removable for hot summer days.
