[Vwdiesel] swapping a good head - DIY head prep??

[LBaird119 at aol.com]

  Maybe it's the flu but I'm not getting why you need to rebuild 
the rebuilt head?  Valves can "tap" and not bend, most of us have 
had the cam timing off that far at least once and got away with it. 
(or at least seen it happen).
  If it's not crashed then all you really need, maybe, is a valve or two 
or so.  It shouldn't be warped should it?
  In actuality you can surface those heads a lot more than most shops 
are willing to go.  I had one that hit the valves when he was surfacing 
it.  No charge, it was "junk" at that point.  We put it on the car and 
it ran great!  The only thing you really have to watch is when you 
grind the valves and/or seats, the valves drop into the head more 
so you really need to shorten the ends of the stems or you end up 
using really thin shims to get them in spec.  With hydraulic valves it
all the more important to end up in range.
