Yea, I figure it will catch some oil. I've ran many of thesae hs81's with Norvel .061's and they've been solbered on plenty... with no ill effects.
As for cooling, dunno. There's some additional gap around the lower cowl. I'll have to look it over again. Maybe just try it?

I still need to get a battery, check balance and wait for the weather to cooperate.
