Not a good idea for a new or rebuilt engine. It needs air flowing
to keep cylinders cool. Happened to a local guy who thought it was neat
to taxi all over the area in his new airplane, overheated cylinders and
it burned a lot of oil from the very beginnoing. He had to rebuild the
cylinders.



I can see that happening at idle speeds but if you run the
engine up to full throttle won't the prop wash provide enough
cooling, depending on the cowling of course.

Actually it will not, a prop turing at full speed with airplane not
moving is not very efficient at all. It also take forward speed to
create enough airflow for cooling. A lot of homebuilts have very tight
cowlings and need a fair amount of pressure to force the air down and
around the cylinders
