gx160 valve will not come out of head

[xtreme_karts]

I have a 14cc gx160 head but for some reason the inlet valve will not come out of the head. Is this normal on them head? I have a gx200 head and all was fine with that one.

Thanks in advanced

due to wear.mis-aligment it happens!!!! if you use, lash cap's on both in/ex will help prevent this,,,,,take emery cloth or file to valve end to remove small amount of metal.usually will come right out...
