I actually was interested in seeing the exhaust port opening and was curious how much porting and port matching could be done to this without compromising the integrity of the aluminum casting.

Is the port opening cast oversize by chance?
 
That's some fine work Phil. Are you doing a run of these?

I need to make some alterations to the moulds for the muffler housing and the front cover, then I'll do a run of 10.
Think I'll cast the extra exhaust outlet flange into all the front covers as pictured in post #8.
