HP Reaper Billet Cylinder Head

At Huddleston Performance we aim to bring the best value to customers when looking at components versus pricing, and that’s what the Reaper Billet Head does. Not the cheapest head on the market, but the improvements you’ll read about below explain the price point. The new HP Reaper Billet Head comes in at $895, and includes: Billet Cylinder Head, Stainless 6mm Valves, Comp 965 Valve Springs, Titanium Retainers, Lash Caps, Billet 4 Bolt Intake Manifold, and necessary bolts.

The HP Reaper Billet Cylinder Head starts off as a chunk of billet turned into a complete cylinder head, with every surface completed by CNC. Once machined, the head uses Durabond Killer B material seats, allowing it to work well with both Stainless or Titanium Valves. Valve stems are increased to 6mm to minimize the occasional exhaust valve failure of smaller stems, while port improvements increase the max CFM through the intake port even with with the larger stem. On the exhaust side, the Reaper Billet has the 2 Bolt header flange pattern to accommodate your existing header, with a 4 Bolt adapter coming soon. These are some of the bigger items, but see the full list below:
