Review on Edelbrock 7501 Performer Air Gap Manifold by Covey Palmer

Item was well packaged and was a pleasure to install. Note to assemblers: It is difficult to tighten the screws in the center section under the carburetor. Get a 1/4" tension set. You may need some adapters, but it's worth it. Torque up to 25 ft-lbs. ONLY oh the last one. The surface area of the collector where it meets the head is very smooth.Clean the surface with solvent or alcohol before installation.Use Felpro gaskets and RTV high temperature silicone for water jacket.
