4 groove valve collets??

I am about to get a set of Ferrea valves. They don't have a listing for the pinto motor for the collets (keepers locks cotters)
I can however specify angle.
I cannot for all my searching find what the standard angle is?
Does anyone know?
Thanks.
Darren.

    Ok - so i got a reluctant reply from Ferrea who informs me that the valves I want take a standard 4 groove valve collet for a small block ford (2.0) and that I need to get them from Ford. (They don't supply them)
    So what 2.0 ford head has a 4 groove collet with a 7deg taper for an 8mm valve stem??  
     
    Don't you hate it when a supplier responds with just enough info to be unhelpfull.

    I should have also added that although your valves have 4 grooves, it's not like you need to use all of them.  Manley valves have 4 grooves too, and that is done deliberately to alter the installed height (of the spring) if desired.  Chances are you'll end up using the bottom 3 just to clear the rocker tip.
