Review on Spectre Performance Universal Carburetor Gasket by Richard Cunningham

That's no good. They work and seal, but they're smaller and I had to trim them with a razor so they don't protrude about 20cm into the inlets (I use a gasket, but it's the same size as the inlets). the Edelbrock Performer RPM - see photo). They'll get you back on the road, but they'll also ruin your intake flow.
