I installed the much sleeker profiled valve cover. With the cap on it protrudes past the valve cover about 1/2 an inch, but it is still handy to be able to remove the cap with it tucked under the intake pipe. I'm quite happy with this mod and it will allow me to design a cowling that passes within an inch or less of the valve covers. In anticipation of flight, I also repitched the prop to a #2 setting, or a finer setting. I should get a significant improvement in performance, can't wait to see!
This was the fun part, my future is bleak and clouded with uncertain days of fiberglass sanding yet ahead. Isn't this why I chose an alumium airplane.... :-(((
