Keith, I wouldn't completely give up on
it. at peak is okay if you are at a low enough power setting. (e.g.
like you will be at higher altitudes)
I have a O-360 at 2200 hours now which looks pretty
clean on the borescope.
I usually am flying low and am VERY ROP (125 dF)
but also have been running at peak to very slightly LOP when
high.
In general the CHT's are 30 dF lower when peak to
LOP.

O-360
Colyn, you're right. I was using the CHT as a benchmark
for whether I was LOP or not, but not how far.
After trying it
again with the lean find mode on the EDM-700, I now see that the spread is
such that I can only get the #4 cyl to 10deg LOP before the engine gets close
to quitting, because #1 and #2 are so much leaner at that point.
So, as
it turns out, close, but not cigar. ROP it is,
then!
