I see the exhaust closing left stock at around 48 ATDC.

Then open the intake later than stock, to eliminate as much overlap as
possible. The  a way late closing point for the intake.

This all makes sense, and certainly sounds reasonable.  Thanks for being willing to sneak out in the workshop, when I "know" you'd rather be working on house stuff :-)
 
As for the actual construction, aren't most of these PP inlets just epoxied in place?  It just seems hard to believe that it won't leak water at some point if you do that.  Is the rotor housing alloy weldable?  Can the port be TIG welded inside and out, rather than epoxied? 

Should have the RV-3 engine home this weekend, but probably not apart until sometime next week. 

Thanks,
Rusty
