Ok, so I finally took my spare engine apart (that I've had sitting in my 
garage from before I ever had my airplane flying).

Rotor housings seem to be in a lot better shape then in my running 
engine. Which brings me to my question:

Is any exhaust porting recommended?

This is a 1986 13B NA. On my running engine I expanded the exhaust ports 
as much as the steel sleeves allowed.
