This is a set of Pontiac GTO 389 cubic inch V8 engine cylinder heads. We did a complete rebuild consisting of a valve job, surfacing & squaring the decks, machining for screw-in studs & guide plates and machining the spring pockets for a set of valve springs for the hydraulic roller camshaft. They will be topped off with a set of Comp Cams full roller rockers.
