Default LS9 Valves in an LS3

I've done some research on this but not finding what I'm looking for. I'm using LS9 sodium filled valves in my LS build with an LSA. I know that I've got to use the LS9 retainers because the groove for the retainer keepers are at a different height on the LS9 valve (they are further down the stem) and the retainers are deeper. I also know that I don't have to use the lash caps on the exhaust valves as they are only for the intake valves which are made of titanium and eat into the rocker arms.

So here's the question....are the keepers (locks, whatever) for the retainer just the stock LS style or are they particular for those valves. Please respond if you know.

Thanks,

Dean

Actually the steel rocker arm is what eats into the titanium valves which is why the steel lash cap is needed but all LS valves use 7° valve locks.
