Same issue I had with my new predator. The 14cc head won't work with those valves. Had to get the valves with bigger stems.

OK, I will do that for sure. Yea my head came with the 3mm valve stems and the old ones are 5.5mm stems. I'll just have to buy new valves and retainers, thanks anyway.

Need some help!!! I bought a 14cc head from arcracing that said the stock valves would work in it. When i took the valves out of the stock head the valve stems are to small for the new head. What size valves do i need to make this head work?

Ok, thank just wanted to make sure, this stuff is new to me.

When advancing the timing 4 degress do you set the valve lash at a defferent gap?
