Valve Stems

[Brogzi]

Does anyone know if the valve stems are any different in an APY head and an AMK head?

Thanks
Kyle.

Valve stems? as in actual valves? 20v turbo valves are all (mostly) interchangeable... by mostly I have seen the collet groove height vary between some (AEB head in this particular case) but APY/AMK/BAM should all be the same valve...
