What series aluminum do the major rocker arm manufacturers use on the Mopar rocker arms?
I read that Dove specifies "7000" series aluminum (on their web sight) for their rockers.

EDIT:
* Harland Sharp / Hughes = 2024-T3511 extrusions (REF: tensile = 68ksi, yield = 41ksi)
* Dove = 7000 (REF: tensile = 58ksi, yield = 52ksi)
The HS/Hughes and the Dove average out (T/Y)to be right at the same ratings.

What material are the others using that you know of? (Comp, Crane, HS, etc.)

What series of aluminum do I stay away from when purchasing?

This coming Fall I will be in the market to buy a set of the aluminum rockers and I am just doing my homework.

Thanks
