Hutch, First, I think a lot of people consider a rebuilt head a valve job and new valve guide seals.
Next, as for head life, I bought my '01 LS650 in July with engine in pieces. 10,460 miles, melted piston, worn journal, cam chain ok. Bought a used head at the local MC salvage yard for $200 (complete head, cam & all). It was from a 86 and was nice.
Cause of failure, High possibility PO missed oil change, or had a "long" interval. Second, cylinder bore was at the tight side of the factory spec, (Machinist said it was right at the small size limit), couldn't measure the piston. Machinist friend said if the oil was poor, and piston was center of the spec or wider, the piston could easily grow and go Kaput.
