Info

The Dart SHP Cylinder Head is cast from A356-T6 aluminum and designed to work with most off the shelf components, so you won’t need to worry about acquiring costly custom components.

  • Bolt on compatibility: Standard valve angle and spacing are retained to allow use of off the shelf pistons and valve train components
  • Multi-angle intake seats and radiused exhaust seats dramatically increase air/fuel flow
  • Hardened exhaust seats are compatible with unleaded gasoline
  • Manganese bronze valve guides extend cylinder head life
  • Assembled with 1.250 diameter valve springs
  • Straight spark plug configuration
  • 180cc intake runner, 64cc combustion chamber, 2.02/1.60 valves, 1.250 diameter springs for flat tappet camshaft

Note:  This head does come with guide plates and studs.
