The Power Adder features a biased exhaust port to reduce restriction and increase power adder performance. The enhanced 1.650 exhaust valve size may require alternative pistons for piston to valve clearance. (see specifications tab for piston suppliers familiar with FED F-Series PA).

Included with the F-Series Power Adder:

  • Raised Intake And Exhaust Ports For Superior Efficiency
  • Unmatched Flow Characteristics In A 10 Degree Valve Angle
  • Softened Chambers (Quench Cut) Included
  • Black Nitride Stainless Intake Valves   2.200
  • Black Nitride Stainless Exhaust Valves  1.650
  • CHE Bronze Valve Guides
  • Standard Spring Kits:

    • Solid-Roller – PAC-1228 .900″ Lift Dual Valve Spring Kit with Ti Retainers
  • Valve Covers with Billet Oil Fill Cap


F-Series Cylinder Heads:

  • Raised runner design on intake and exhaust ports allow cylinders to fill efficiently at high-rpm without altering low and mid-range performance.
  • Exhaust to valve port exit is on-center with valves for unmatched flow characteristics in a shallow combustion chamber and 10° valve angle.
  • High-efficiency water jacket.  Optimally reduced water jacket for strength, efficiency and optimal cooling capability for all applications, even endurance racing.
  • 0.750” deck structure. thicker than all stock and most aftermarket castings.
  • Extended intake flange accepts all standard manifolds without modification.
  •  LS7 bolt pattern accommodates standard header designs using 2” or larger headers.
  • Proprietary modified A356-T6  aluminum casting. We modify the mag, iron, and silica levels to accommodate for the high level of stress on the alloy. This allows us to maintain proper hardness while still having elasticity to flex a small amount under load.
  • 100% designed, tooled, cast, and machined in the USA.
  • Dry deck or solid castings available for an additional fee. (Call for details.)

F-Series Valve Covers Included:

  • Valve cover design inspired by the SB2 pattern, clears shaft mount rockers and springs with larger diameter/higher lift packages.

  • -6orb water crossover ports allow for better cooling capacity and more flexible installation/plumbing options.
  • -16AN ORB Oil Fill cap included.
  • 319 aluminum alloy cast valve covers – the alloy used in most aftermarket and stock cylinder head castings.
  • Includes a baffled vent section, compatible with stock PCV/emissions components.
