     Since everyone is going on about compression I thought I would 
     continue the topic and ask a little advice.  Yesterday I went out and 
     purchased a compression gauge and put it to work.  The readings I 
     received where 20-20-40-60 on my 70 B.  This is the reading received 
     from a car that has been sitting for 2 months.  Not good huh?  This 
     would probably explain why I am getting little vacuum from the front 
     SU.
     
     I purchased the car about 2 months ago.  At that time it was pretty in 
     good condition.  I drove it three hours from the place I purchased it 
     to its new home, all without a hitch.  I then drove it 3 or 4 short 
     trips, to work and out to eat.  At which point I decided to do a 
     little maintenance.  The previous owner had the car for 13 years and I 
     don't believe he had changed a line or gasket in all those years.  I 
     replaced the fuel lines, filter, etc...  Then I took her out a couple 
     more times.  This is where all the fun starts...not!  The float bowls 
     failed and I started seeing a 3-4 inch puddle of antifreeze on the 
     ground after shutting her down.  Disappointed, I decided to get 
     industrious and to make an even longer story short I have since 
     rebuilt the SU's, replaced the all gaskets from the manifold to the 
     airfilters, statically timed, gapped the valves, and replaced the 
     water pump.
     
     Now the bugger will not start!
     
     My plan is to remove the head this weekend and have it serviced next 
     week.  Does it seem like just a valve problem or rings too?  If this 
     is not a lead free head (don't know), should I have this one machined 
     to lead free and/or ported and polished, or buy another head?  Any 
     suggestions where I might have it serviced here (DC area) or send to 
     reputable servicer?

     PS  FYI I just switched to the digest this morning (can't read the 50 
     plus messages everyday at work, though I would love to).  I don't know 
     how this will affect responses.
