Totally agree with the piston-before-valve comment.  Ask Rick Byrnes how his
pistons looked after a half-dozen passes with the monster turbo boost he was
running.  The weak link in the thermal system is the piston crown, not the
valve material. 
I think I heard Rick say that once...

RE: 1750F EGT

My engineering book shows that the melting temperature of Aluminum (ie.
pistons) is 1250F
Iconnel is 2450F
Stainless Steel is 2750F

I think I'd worry more about the pistons than the valves.

I know the pistons are an alloy of Aluminun, but still.....
