What Epoxy are you using? I need less than a peanuts worth and don't want to buy 6 oz as Ill never use it all. Intake roof has a <BB sized break into the head bolt boss area. Gonna fix the window with epoxy and the head bolt seat with a hardened washer and some epoxy under it and then torque it down so it hardens under the bolt stress. The bolt torque keeps compromising the repair.
