What is the boiling point of BRASS

[yellow90tsi]

I have a quick question, in my cast manifold, i had to drill it for an egt guage. Well when i did this someone put the wrong size drill bit back and my hole was bigger than needed to be. Well so i am going to buy either a brass or should i buy a steel bushing 1/4npt to 1/8npt bushing? I like the idea of brass, just not sure the amount of heat it will withstand. Thanks guys.

Awesome site thanks man, do u think brass or steel then? Either way if the brass melts at 1750 then my valves will be close then also right?
