Military-Vehicles: [MV] VALVES AND UNLEADED FUEL???

Hi List!

I have a question concerning the use of unleaded fuel in older engines =
that were designed for leaded fuel. I have been told by some that if you=
want to use unlead in these engines you will have to use an (expensive) =
octane booster additive or have the valves changed out in the engine. =
Not being very experienced at major engine work, I can honestly say that =
I don't have a clue. I figured that you guys could set me straight. I =
am about to have a valve job done (because of a burned exhaust valve on =
#4) and figure that if they need to be changed then this is the time. =
Any information or opinions on this will be very helpful.

Thanks all,
