Day two of bolt removal. The exhaust manifold I pictured, isn't the one giving me issues. I'm having to drill out two bolts. It's a nightmare. Anyway, when I put on the new manifolds I was instructed to use a gasket, which I got one at Napa. I know the factory used a high temp bead of silicone. What do you guys recommend?
