After all the responses both on-line and off-line, I've come to my
senses. The consensus is that I should cut back on my coffee consumption
and be thankful that I have one of the best V8 mechanics in this part of
the world doing the job (Greg Hyman @ Autofirme, Pawling, NY). I just
needed recalibration... that's all.

I did not consider a boneyard replacement. After searching the archives,
I understood my options and that a rebuild is probably more costly.
However, once it's complete, I'll have a known quantity. To me, a
boneyard replacement is asking for more trouble, introducing more
unknowns. At least now, I know that the top end is in good shape and is
done properly.

I'll get the details from the mechanic and pass them along to the list.

My thanks to everyone that responded to my post for keeping me in the
proper frame of mind here.
