EDB-D heads for early F-Code Supercharged car. Raised "EDB" casting with Stamped "D". Large "X"'s cast in to the deck surface in two places on each head. The catch is the Exhaust Ports have been ported into a Round Shape to match tube headers instead of the original rectangle port. Factory Exhaust Manifolds should seal with a gasket. Intake ports have been ported and the chambers polished. There are dings on two chambers where something bounced around in the cylinder. Complete with valves, HD springs, and aluminum retainers. These heads "have been modified" but correct for F-Code. $2,000. Email or text for pictures: pmfleischman1@yahoo.com or (806) 441-6094.
