    Dumb question- I have a Performer RPM Manifold, and I just installed a new 4 bbl gasket. It hangs over the inside edge a little. Square bore (open) gasket. Do you guys trim yours a little or just bolt it on?

    I'd run it like it is. If it bothers you, trim it! 65'

      No, It is hanging over the inside edge. I'm thinking fuel might get caught on it. The old gasket seemed to have some fuel saturation on it.

        Are we talking about Carb Gaskets or Girls Hygiene Habits?

              Trim the gasket if it won’t open up any passages on the carb. Place the gasket on the carb before and after u trim it. Kim

                Trim it. People spend hundreds to port match intakes and heads. Why leave a big gasket on there to fudge things up below the carb.
