Cracks in Head on 69C

[JAMES SCHULTE <schultejim@prodigy.net>]

Listers,
I talked with my machinists today about my 69C Head.
He said there are 3 cracks just above where the spark plugs screw into the 
head. He said they are not a problem and he could repair them. If I didn't have 
them repaired, the head might leak oil from these areas. Anyone have experience 
with this sort of thing?
