Roller Rocker ?

[national86]

I need some help identifying a set of roller rocker. I bought these about 10 years at a swap meet, I even forgot I had them. They are red anodized and they say Kenne Bell. I would like to know the ratio and if they would fit and work ,without machining the head. So if someone has and old Kenne Bell catalog I would appreciate if they can tell me. If they do not work for my car I will put them on ebay. I will try to post some pics.

Are there any serial numbers. Kinda hard to tell since all they are really are "red anodized rockers".
