Next fun task, exhaust stud replacement. These are a bitch and a half. They always corrode and seize in the manifold flanges. They are made of some ungodly hard material so they are very hard to drill out. I've tried heat in large quantities and they don't budge.
No in progress pics here, but I cut it flush with the flange, center punched it, then drilled it straight through with a 1/8" bit. Then I drilled it most of the way through with a 1/4" bit and punched it out. Only three more to go...
