I have had bad experience with no name valves on gy6 150. These valves have names, but still: set intake to 004 and exhaust to 005. If you overrev it and it starts "clattering", you had better adjust those valves QUICK! YOU CANNOT RUN VALVES LOOSE AT ALL ON GY6 or it may break the valve!I used a little marine grease on the valves (both sides of the seal, along shaft) as well as put on oil, and turned over the motor a few times by hand, before startup. I will take it easy with this head for 100 miles, but 500 is more optimal. I literally have broken valves for seemingly no reason on GY6. But my first head made it 20000 miles, next 2 made it 1000. I am hoping these valves with little stamps on them are stronger than the ones I had gotten from Goofball, their competitor.Glixal is the best company on here offering parts. the other one is xpro. otherwise you are getting bad parts
