This is our Spec Rebuilt Cylinder Head fully machined and assembled at DSM Graveyard Inc.  All of our Spec Head Rebuilds go through a full cleaning and tear down, and go through the glass bead system for optimal quality.  Next, the heads go through a full inspection, measuring, and testing, and then it on to the machining process, where we refinish the seats, guides, and the deck head surface.  Lastly, we flush out the cylinder heads in our final wash Safety Clean Tank, and assembly the head with fully recondition valve train.  All valve train on our Spec Heads have been completely refinished and tested, including valve springs, valves, keeps, retainers, and valve seats.   Our Spec heads are a lot more than a quick shop rebuild, these heads are build with quality and consistency in mind.
