Alright guys. I have an exhaust leak and I'm rebuilding the carb right now so I thought I might as well fix the exhaust leak while I have the carb off. I need to get the manifolds off but the bolts are stuck in there after heat cycling for 41 years. I managed to get two of them off on the far right but one on the left of the middle part of the intake manifold has successfully had its head stripped. I don't know how to get it off because the only way I could think is to drill it in and get a removal tool but I can't drill into it because the intake manifold is in the way. Do you guys have any ideas?
