I'm having a hard time conceptualizing what happens at the interface of the prop governor, the air ramp and the air seal fabric. It seams like a big leaky hole to me. Does anyone have pictures... or wonderfully descriptive words... of that area?

You pretty much summed it up. Seal it with rtv and seal material as best as you can. Keep fiberglass cutout snug except for control arm area. Think of cowl movement locking prop control up. I have everything else tight and no overheating(over 400F for me) at full gross 120 kt climbout on a 100F day.

Jeff, you need to do the best you can in sealing the area. I have attached pictures of mine but it does not show how I did it that well.
Use combination of rubber seal and RTV.
The hole you see above the cowl ramp is in the high pressure area and does not effect the seal.
Hopefully some has a better pictures/method for you.

One thing to keep in mind is that unless you seal an end of those ramps, the air can leak under them to the outer end which is in the low pressure area. So the hole above the governor may matter if you don't contain the air.
