Hi Larry,

Thank you for writing.  Just doing the heads is certainly
attractive because of the time savings.

The cylinders are already disturbed.  They came out
of the case as I was pulling the heads.  They're still
on the pistons though.

I didn't really want to get into this, but... I did have
an oil pressure gauge attached to that engine which seemed
to indicate everything was fine.  Having now driven with a
different engine I have become aware of how slowly the oil
pressure drops with time as the oil heats.  I am
not certain that I allowed the old engine to heat enough
before recording oil pressures.


To summarize:  I never got any indication my oil pressure was
a problem.  My gauge numbers were good but I'm not sure I
trust them.
