Features

Solid PC Gasket KIBBLEWHITE (manufacturer part no. 71006-4): valve guide seal machined from PTFE designed for vintage and road engines. Intended for classic and touring enthusiasts seeking reliable sealing on Shovelhead-type cylinder heads, this seal provides thermal resistance and low friction without unproven technical surprises.

  • Material: filled PTFE — mechanical property stability up to 500 °F (≈260 °C).
  • Design: double spring profile to maintain continuous tension on the guide and valve stem.
  • Applications: intake and exhaust.
  • Dimensions: stem diameter 5/16" (≈7.94 mm) · outer diameter 0.600" (≈15.24 mm) · length 0.510" (≈12.95 mm).
  • Manufacturing: Made in USA, machining and finishing tailored to the constraints of vintage cylinder heads.

Specific for Shovelhead with thin valve stems (usage reference indicated: 0.3090" intake). Examples of compatible models: Harley-Davidson FXWG 1340 Wide Glide (1983), FXS 1340 Low Rider (1983) and FXR 1340 Super Glide II (1983). Ideal part for interventions on valve stems where sealing, durability, and friction control are sought.
