      I recommend this product
      An open and shut case

      Rebuilding a worn out '67 TR6R top to bottom, so a valve job is essential. Kibblewhite's race-proven Black Diamond exhaust (and intake) valves will ensure solid performance and reliability for the next 50 years. There are cheaper valves, but "cutting corners" also cuts long term performance. Use the best and ride with confidence.

      The valves were perfectly made.

      No need to do any lapping at all. I also had new springs I bought and they are great too. Never been a problem with anything I get from Lowbrow. Thanks Tyler for your great parts seleection and fast service. Happy in Texas ! Todd Havely
