There were several postings last winter about not enough heat in
320/360's.  Someone mentioned that it was common that builders
were connecting the heat scat tubing to the wrong connection
point on the heat diverter valve.  While I live in a rather hot
climate there were a couple of high altitude flights I made last
winter that could of used a little more heat.  While poking
around with the cowl off one day I noticed that the builder of my
320 did in fact connect it wrong - so I corrected it.  Well, now
I can roast turkeys in there!  In fact, I had to put a cover
plate over the inlet to the heat system this summer because the
leakage in my 10 year old diverted valve was enough to make it
very uncomfortable.

Anyway, I suggest you take a second look at how your tubing is
connected because it does make a difference.  If connected per my
very crude diagram below, you can get from 0 to 100% of the
heated air.  If connected any other way, you will get heated air
mixed with free air in the cowling area.
