are you running long tube headers? iv seen guys with long tube headers put a heat shield over the brake booster to protect it from some of the heat the headers put off. and I might be wrong about this but I wanna say the zr1 boosters had a metal housing? I could be totally wrong about that but its worth looking into

Personally, I don't run any store brand aftermarket parts. I'd snag an ACDelco/GM one online, from a quick search it looks like they're readily available.
