Dan:
I'm afraid that the head is toast. You might try a leak down test, but the
valves are probably beyond their service life. I would tend to the braking
system first and then think about pulling the head, and doing a first rate
three angle valve job, using bronze guides, and S/S valves. I would also
check and see if it does in fact have hard seats installed. It not, then
now is the time to do it.
Cheers:

seem to remember someone talking about installing the battery in the trunk
a while back. Right now, there are no brackets holding it in!

cylinders are showing 75-80 and one is at about 55! Could this one be a
burnt valve? Its a lead-head (original I think) and has been run on
unleaded gas with lead additive for a while by the PO. What are the chances
that a new head will solve the problem? How BAD are these compression
numbers? Should I suspect the well-used guage or are they bullet-proof? The
car runs strong but does have a slight miss, I'm thinking probably from the
one weak cylinder.
