• Valve Face Angle: 45 degrees (standard for Shovelhead applications).

• Standard OEM: Traditionally made of steel; many original "New Old Stock" (NOS) units from the AMF era were manufactured in Japan.
• Modern Replacements: Often feature a Black Nitride coating, which is harder and more heat-resistant than standard steel to better accommodate modern unleaded fuels.

Fitment: This valve fits the following specific Harley-Davidson model families within the 1966–1984 year range:

• FL / FLH Series: Includes Electra Glide, Super Glide, and Heritage models.
• FX / FXR Series: Includes Low Rider, Super Glide, Wide Glide, and Sturgis models.
• Engine Types: Fits all Shovelhead engines; specifically mandated for 1980–1984 models that required nitrided valves to handle unleaded fuel.

Please make sure of fitment before buying.
