Product Description

Every intake port, every exhaust port, every valve bowl and every combustion chamber is 100% CNC machined on special, dedicated Pro 1 castings. Our 5-axis computer controlled machining centers produce compound curves and complex shapes that no human could duplicate with a hand grinder.

Features:

  • Premium alloy: Dart aluminum heads are cast from virgin 355-T61 aerospace alloy for superior strength and integrity.
  • Bolt on compatibility: 2 degree rolled valve angle and standard spacing accommodates all stock accessories.
  • Heart shaped 121cc chambers improve combustion efficiency.
  • CNC machining ensures that every chamber has the same volume so that every cylinder maintains equal compression.
  • Raised spark plug location improves flame travel for a quicker, more complete burn, producing more power.
  • Multi-angle intake seats and radiused exhaust seats greatly improve air flow.
  • Hardened exhaust seats are compatible with unleaded gasoline.
  • Exhaust ports raised .300” to improve flow (requires 1” longer head bolts next to exhaust ports).
  • Spark plug holes are machined for gasketed 3/4” reach plugs.
  • Manganese bronze valve guides ensure long term reliability.
  • All cylinder heads sold individually.
