Up for sale is a rare, matching pair of vintage factory original OEM cast iron Early Hemi cylinder heads complete with their original factory-attached exhaust manifolds. Displaying crisp factory engineering stamps including casting number 539, these genuine mid-century hemispherical combustion chamber assemblies feature original valves, springs, and guides, making them an incredible, unmolested survivor core set for your classic drag strip restoration, rat rod, or traditional period-correct hot rod project. Preserved in solid barn-find condition with typical surface oxidation, grease, and dust from decades of dry warehouse storage, this matching left and right side set provides the foundational structural integrity and legendary heavy-walled vintage performance that modern aftermarket pieces cannot replicate. Please review all high-resolution photos carefully to confirm exact application dimensions, engineering codes, and component conditions before purchasing.
