Manifolds

Ultra Pro Machining offers two styles of manifolds that are precisely matched to the intake ports of our heads by CNC machining the flanges to the manifold face of the head. Our dual injector manifold is fabricated from steel for strength, it is the ultimate in manifolds giving the engine equal mixture distribution to both cylinders. You will need two for a complete engine. Our single injector is made from aluminum is very light, is simpler to setup, and more economical.

Billet Rocker Boxes

Our Rocker Boxes are CNC machined from billet 6061-T6 aircraft aluminum. They are designed for use with our heads and
rocker stands. The top cover has been counter bored to hide the bolts. Together with our heads they look as fast as they go!!

Billet Rocker Stands

Our rocker stands our manufactured from billet 6061-T6 aircraft aluminum. They have steel dowel pins already installed, which is important for proper alignment with the rocker arms to prevent binding. The pushrod clearances have already been machined into the stands for your convenience.

Cylinder Heads

The current design is a highly engineered product resulting from years of testing, racing, and winning. Our Top Fuel Harley cylinder heads are manufactured completely in house. They start from a proprietary raw billet extrusion and are then meticulously machined on three of our CNC machining centers dedicated to this job. Next we install our in house bronze guides and beryllium valve seats. All our finish seat profiles are manually cut on a Serdi machine with specialty fixturing, this insures perfect concentricity, which translates to a tight seal and more horsepower. Finally some delicate hand blending extracts peak performance from the cylinder head. There is somewhat of a symbiotic relationship between the valve and seat so included with your heads is a set of custom ground valves that finish the package. The intake valve is made from titanium alloy. The exhaust valve is also is made from a high temperature nickel steel alloy commonly known as Inconel.
