Hedman Hedders, the world's original and leading production hedder manufacturer, builds an equally powerful set of 2" Hedders that let you plug your monster ZZ502 into 1970-81 Camaros, 1968-77 Chevelles, and Malibus, and 1970-77 Monte Carlos.
Hedman's #66103 with HTC Ceramic-Metallic Coating #65103 without coating) have been meticulously designed to be the best fitting, most durable hedders you can bolt on. The hedder flanges have been correctly trimmed to fit around the base head bolts on the aluminum heads. A common obstacle when installing aftermarket hedders on the GM Performance ZZ502/502 crate motor. This pre-notching at the factory eliminates the need for the installer to notch the flanges themselves, significantly reducing the installation time.
Hedman's ZZ502 Hedders exhaust ports match the aluminum heads for optimal exhaust flow. They are fitted with heavy-duty .35" hedder flanges, a 3-bolt triangular flange collector, and come complete with all the gaskets, fasteners, and reducers that weld directly to the exhaust, and bolt right on to the hedders.
