just consider how much aluminum expands.. Valve seats, stellite or hardend
steel, are pressed into the head.
Aluminum melts at 1220F so you're still a way away from melting but that's
one of the main causes of dropped valve seats....
Also remember that the valve guides, bronze/silicone, also have different
expansion properties so if you run
your head at a high temp for a sustained period expect things to fall off.
To Chuck's point though, just drive it but also develop a profile of what
your engine's characteristics are
so that when you see it jump to 500F you can then say "this isn't right."
