Slant six heat riser block off plate

Are you using a stock slant six exhaust manifold with an intake manifold that does not have provisions for the heat riser? Block off the heat riser with this 1/4" thick steel block off plate. These are made in the USA. We're using this with a Clifford intake manifold on the turbo Dart project. If you are using a Lynx, Weber side draft, or other manifold, please check clearance before ordering.

This will not fit between a stock exhaust manifold and a stock intake manifold, nor will it fit to manifolds that bolt to the stock heat riser such as the Offenhauser four barrel. It is only for use with aftermarket intake manifolds paired with a stock exhaust manifold. Fits all factory Chrysler, Dodge, and Plymouth single exhaust slant six manifolds - 170, 198, and 225.

Street legal only on 1975 and earlier vehicles. Plate only, gasket and bolts not included.
