871 Blower Base Gasket

From 4-71 to 14-71 SCE has blower gaskets that seal! Blower cases "move" when they're under power, after a pass you can see traces of fuel and in some cases slip a feeler guage under the blower case when thin hard gaskets are used. SCE gaskets are thicker and more compressible, this allows the blower case to stay sealed during a pass, sending the boost where it belongs, down the manifold.
