Slant 6 rocker arm metalurgy

I don't know any more about them than yall do. I called them last year and they said they had 1.6 non rollers for the slant for like 300 or so. They didn't say at the time they were reworked though, but that makes sense. Bill, the rockers are some kinda stamped steel, so I see nothing that would make them non weldable. I find it strange that the company has had these offered for a while now and no one really knows anything about them. That's a big red flag to me.
