Yeah, I am sure.  The 71 only had 60k on it when I first bought it and I
know there was no head work done on it while it was in NY.  Besides the head
has the following cast into it.

311.101.375
VW  71

The "VW" is the roundel.

The hi-rev springs were all that was available new when I was shopping. 
What do people do that run dual springs?  They are much higher pressure that
the single springs.  Even the hi-rev ones.

Going to go pull that valve out for a "look see".  Not that I expect to see
much.  Will have to start looking for another head, I guess.

The blow-by might explain the lower compression on that bank.  #3 and 4 each
had 120 psi.  #2 had 90psi and #1 had 110psi.  I will lap in the cylinders
on this bank.  I think I will leave the other bank alone.  I will check on
the availability of stock springs.
