So tried to take photos, of the gap being measured. But camera did not resolve the fine graduations on the scale that I have. I think anything more is moot, though. If there is no easy correction, then I will leave well enough alone. The plane is a joy to fly, gaps and all. I can always tell people that I am working on a Cooling STC!

Not unless we trim a fair amount from the lower edge of each upper cowl half. If you look up a few posts at the photo titled: left_side_horizontal_cowl_seam_117.jpg you can see that the horizontal seam between the upper and lower cowls is tight. So I think any downward adjustment of the latch position on the lower cowl (and I don't know if it is adjustable or not) to pull the upper cowl down and close the gaps will cause the upper cowl to overlap what should be an exposed portion of the lower cowl. It would, I think, trade one misfit for another. On the bright side, I have great low cylinder temperatures. So, I could either attribute that to the superior job Gary did for the prior owner installing the rebuilt engine and building new baffles, OR I could attribute them to enhanced airflow due to the gaps at the corner of the cowling. Since I would rather not compliment Gary, I will point to the cowling gaps.

You are 100% correct, your upper to lower cowl gap is correct and tightening the latch would do damage not improve what I have seen in the pictures. Gee... I hope Gary takes what you said as a complement - He does not read very well and jumps to conclusions. I took it as a complement to his workmanship ;-) Off to the AP to work on my lame bird. BIRD! Did some one say BIRD. Keep an eye open during pre-flight. There are hundredths of birds nesting out there... I pulled three nests from planes so far. Did you put foam, in your wing tips, where the counter-balance weights exit?

There's no room for meaningful further closure. I show photos of both the left and right sides in the big block of images I attached a few notes above. You can see that the seam is tight. If this is the worst issue I ever have with 74429, I will be a lucky pilot! Thanks again for everyone's input and help.
