Oh, I have heard about milling down the seating surface as well, but anyway its not the intake hitting the master cylinder its the upper corner of the carb where the diapham housing for the vaccum secondaries, is hitting the brake booster. Thats where the problem is, so I am looking at converting to manual brakes or modify the booster set up, but I am open to ideas. <img src="/forums/images/graemlins/cheers.gif" alt="" />
