Well thanks for the info on the leaky heads, sounds like it is something
that should be taken care of immediately.  I was wondering what luck
people have had with the various replacement heads available.  I am
particularly interested in the AVP rebuilt heads.  I was wondering what
the quality of these heads was, and if you need to do anything to them
before you install them (i.e. do they come ready to go with valves.)

Thanks,
Patrick
