Exhaust valve/stem question...

[Canis_Major]

Are the older valve stems and newer (Angel Force) valve stems interchangeable? In other words can I use a newer valve stem with the older (original) valves? And, can the older valve stems be used with the AF valve?
newer stem on left - older on right

They are not interchangeable because the valve body is different to help with the increased airflow.

Thanks Trigga - I figured as much...

FMA-
Bob says the new stems will work on the old valves and MT valves.

Hey Canis did I have the wrong Valve stem in the marker i traded you?

Thanks for checking with Bob!
I've got 4 markers (3 G7flys and an 06 speed). 2 have the MT valve and valve stems, 2 have the previous generation stems and valves.

I think the marker I got from you had the MT valve and the newer valve stem.
(Thanks!)
