Well I must agree.  Over the christmas break, I talked with my dad about 
rebuilding VW engines.  He had told me that his motors lasted only 50-60k 
miles.  I was wondering why this is the case, and basically he only replaced 
the really bad parts.   He would reuse everything else, and I'm sure that 
many of these parts were borderline at best.  
        I had posted about the trip about cams earlier, but I had to replace 
mine, it was worn real bad.  The real problem with the engine that I'm 
rebuilding is that there is pieces of bearing material everywhere.  This has 
worn out the oil pump as well.
        The heads I have are cracked between the two exaust seats, and thus 
are junk.  I think it is good advice to replace your heads with new stuff.  
It just seems that a dropped seat or a swallowed valve is too much risk with 
all the other stuff which is heavily invested.  
There's my 2 cents.
