 ALL F-Series Heads Include:

  • 100% Designed, Tooled, Cast and Machined in the USA.
  • A357 T6 Aluminum Castings – T6 heat treated, low silica alloy. Similar in strength, machine-ability and weld-ability to 6061-T6 billet. Superior strength compared to all commercially available castings. 20% stronger than similar high-end castings made from A356. A357 is the same material used in most aftermarket engine blocks along with many cast aerospace components.
  • 0.750” deck structure, thicker than all stock and most aftermarket castings
  • High efficiency water jacket – by increasing efficiency the overall water jacket has been reduced for overall strength without sacrificing cooling ability for all applications including endurance racing.
  • Raised runner design on both intake and exhaust – Raised runner design allows for more efficient cylinder filling, better high-rpm operation without sacrificing low and mid-range performance. Greater flow characteristics, especially when combined with our shallow valve angles. Intake flange is extended to allow all standard manifolds to fit without modification.
  • Exhaust port exit is on center with valve – Substantially better flow characteristics. LS7 bolt pattern moved to accommodate all standard header designs using 2” or larger headers.
  • Proprietary valve cover design – Enlarged valve cover based loosely on a SB2 pattern allows for more rocker clearance when using solid rollers, more spring clearance for larger diameter/higher lift packages. Valve covers included with purchase of heads. See valve cover section below for additional information. Valve covers are doweled and o-ringed for superior sealing and serviceability.
  • -6 ORB water crossover ports – better cooling capacity and more flexible installation/plumbing options.

Valve Covers:

  • 319 aluminum alloy cast valve covers – same alloy used in most aftermarket and stock cylinder head castings.
  • Baffled vent section – Compatible with stock PCV/emissions components.
  • -16AN ORB Oil Fill cap included.
  • Available with built in coil mounts or without coil mounts.
  • Available in two powder coated finishes. Fully machined versions available upon request.

Solid Roller Options:

  • All F-Series Solid Roller cylinder heads available with shaft-mount, roller tip rockers.
  • Available for on-center and 0.180” offset lifters.
  • Solid roller heads will accommodate up to a ½” pushrod.
  • F-Series shaft-mount rockers will be available as standard catalog item.
