Propane Nytro Valve Guides (need better ones)

[n2otoofast4u]

As Im getting farther into the motor on my propane nytro I have realized that the valve guides on the exhaust side are HAMMERED. Im assuming that this is because the propane has no lubrication affects like gas does? I will call Val next week when hes home from expo, but thought Id start by gathering some Ideas here. The valve stems are perfect, but the guides themselves are shot. Does anyone offer better valve guides than OEM? Anyone with propane (or gas for that matter) ever seen this kind of thing? Id REALLY like to get this thing on the snow before the year is out. (havent got hardley any miles on it since I bought it) But with workin out of town and the forever growing list of things that need fixed its not looking good. Any suggestions?

the motor that chuck did only lasted a few rides and head cracked again (nice waste of $6000). kens marine had mike rebuild it with a new head after that.
