Product Details


  • C630 Racing Bronze material contains 80% copper alloyed with 5% nickel and 10% aluminum
  • Engine Builder Valve Guides were designed with the price conscious builder in mind; meets all the KPMI tolerances but with reduced toughness and wearability, compared to C630 Valve Guides
  • High copper content (20% greater than traditional manganese bronze materials) gives excellent thermal qualities
  • High nickel content makes the guide harder and more wear- and corrosion-resistant than other bronze materials
  • Corrosion resistance is an especially critical element of guide life with the new pump and performance fuels sold today
  • Aluminum content brings characteristics that make the guides especially compatible with aluminum cylinder heads
  • A radius at the transition from the nose profile to the main body of the guide prevents galling on installation
  • Kit includes two valve guides except noted otherwise
