valve seat material?
Anybody know what material the stock valve seat inserts are on a 2002 zo6 head? Doing my on head work and want to get the right cutters for the seats. Will be doing my own head/cam/clutch upgrade as soon as I get the heads done. Doing my own porting and polishing. Will post before and after dyno runs as soon as I'm done. :auto:

Most inserts are something called "Stellite" (sp?), which I suspect is simply a hardened steel compounded in such a way to minimize expansion and contraction with temp changes.
