OEM Rocker arm suppliers

[Bruce2]

I am attempting to identify the OEM rocker arm / bucket supplier for many current powertrains in North America and Western Europe. My research to this point indicates many small companies, some that I have never heard of. Does anyone know of a resource for this type of information, or have detailed knowledge of OEM rocker suppliers?

I've heard of a bunch of small companies that do it. I know that Burgess Norton does a bunch of OEM rockers (piston pins too).

IR Torrington supplies rocker arms to some oems. What do you need it for?
