[Fot] Unleaded and valve seat damage: Myth???

[Mark Eginton]

As an old car buff for too many years, I can't say I have ever lost a 
valve to unleaded gas. From flatheads through muscle cars including 
vintage motorcycles and 40 years of driving this Triumph. I thought I 
would be safe on this engine and go ahead and do the valve seats when an 
old machinist I like to use told me its all a myth and that he has never 
seen valve seat damage either. "I'll be glad to take you money..."

Just thought I would ping the list before closing on this decision.

Best,

M
