I guess they are 1.6...these are just roller-tip and I'll have to find my old receipts to verify part number. They may be the Magnum but I think they weren't rated for my spring pressure. It has been 7-8 years since I bought them. Lol. Hell, they may be Comps, too. Lol.
(EDIT)--They should be the CompCams Magnum, (Or the 7200 Steel Roller Rocker Kit from Mondello, which is the CompCams kit retagged IIRC); and yes, I know all about the Mondello controversy of the last several years.
At the time I was buying these parts, though, I hadn't heard or read any of the info about the split between Joe and rest of company, and the controversies surrounding the company; I did, however, not have a bad experience at that time.
