This item fits the following models:

• Guide profiles are designed to be as clean and unabstructive to the airstream as possible, while maintaining critical cross sectional thickness in high temperature areas, promoting both high performance and endurance
• C630 Racing Bronze material contains 80% copper alloyed with 5% nickel, and 10% aluminum
• High copper content gives excellent thermal qualities
• High nickel content makes the guide harder and more wear corrosion resistant than other bronze materials
• Corrosion resistance is an especially critical element of guide life with the new pump and performance fuels today
• Kit includes 2 valve guides except noted otherwise
