Brake line close to header

[smn69]

Quick question:

I installed headman headers on my sbc and one of the tubes on the passenger side is very close to the front brake line. About 1/4 of an inch. Is this to close? I am worried about getting the brake fluid to hot. I was wondering if wrapping a little header tape in this area will keep it from getting to hot, or if there is some other type of heat barrier that will work between the header and brake line? It is right in the area where the brake line has bends in it to clear the frame rail after it comes across the cross member. Any help would be appreciated.
