[TR] Valve Composition

[Bob Labuz]

Terry,

No answer on the valves composition or size, but I used the bronze 
guides from TRF for my 3, 4 and 6. So far so good.

Make sure your machine shop installs them correctly. I believe a bit 
more clearance is required for the bronze guides than the stock cast iron.

They will need the valves before the guides can be installed.

I would stick with the same valve stem diameter as what is currently in 
the head.
