Black Diamond!

By Charles D. on  Verified Purchaser

Great product! I lapped my new exhaust valves for a nice seat and tested the seal with gas, no leaks. Put the motor back together ran the first 100 miles and did full engine and transmission oil change. I am up around 250 miles on the rebuild now with NO ISSUES! I was concerned when I first got them that the thicker more bulky head on the valve could cause piston slap or even intake and exhaust valves colliding. Neither were the case. Sounds better and has more power than it ever did before. Next update I will do will either be for valve related failure or the 10k miles marker on my rebuild. My money is on the 10k miles and onward. I recommend this product.

Questions & Answers

Will these valves work with stock factory valve seals?

By Anon.

Yes, unless otherwise noted in the description after you select your exact machine from our fit guide, these valves are designed to work with all remaining valvetrain components, including the valve seals.
