But these are genuine VW heads from my 71 Fasty.  I personally rebuilt them
with new guides and new VW valves all around.  Only did a 3 angle valve job
to the seats.  Only non-stock part of the heads are the springs.  They are
bugpack hi-rev single springs.

Did not lap the cylinders in.  Have never heard of doing that.  I personally
resurfaced the head surface, though.  The P&C are new. I was really
surprised by the amount of blow-by.  Maybe will try lapping them in.  Not
sure what else to do about that.

I will have to try to find another head.  I think I will try to use this
head until the snow flies and I get my winter car out.  Then I can redo this
engine again. 8^(  OR at least the head.
