  • 64cc Chamber
  • 2.02/1.6 Valve
  • Straight Plug

  • Hardened exhaust seats for unleaded fuel compatibility
  • Bronze valve guides
  • Manufactured with aircraft quality high grade aluminum alloy
  • Multi-angle seat design for improved flow at low lifts
  • Advanced port design for improved flow at all lifts
  • Advanced combustion chamber design allows superb flame travel and burn
  • Additional pushrod clearance machined along outside port walls
  • Can use either early or late (Vortec) intakes
  • Can use either perimeter bolt pattern or center bolt valve covers
  • Threaded accessory holes in ends of heads
  • Retains stock 23 degree angle and intake/exhaust bolt locations
  • Thick deck to resist warping and allow for additional milling if desired
  • Does not require offset rocker arms

These heads will work for all small blocks including 400s (no steam holes). Heads are drilled for both the earlier style intake bolt pattern (pre '87) that had all bolts going in at an angle and the newer Vortec style that has 4 on each side going straight down in. Will not work with stock intake manifolds, must use an aftermarket raised runner intake.
