Ram Air 4 pushrod strength

Searched archive's didn't find much info.

I have a new set of 11/32 RAIV pushrods that I bought 100 years ago at a HO Racing garage sale

What are the limits on these critters I know extra diameter over 5/16 is a good thing but at what spring rate / RPMs does the welded on ball split open the tube or the pushrod bends / fail at?

Anyone know wall thickness or material on these?

Were there very many failures in the OEM application's?

Thanks
