How hot do you think the head of the F20 gets during high stress application? A few hundred degrees? Say near the intake or exhaust ports.

Well, the intake ports will be somewhat cooler than the exhaust. Really depends on how coolant flow is routed. 200-300F on the intake and 300-400F on the exhaust (in the port) is probably not unreasonable. But, I really don't know for sure, you'd have to instrument it to be certain.

Why do you ask? Trying to add something to the head, maybe made of composites, or plastic?
