4 years ago when I rebuilt my 261, I got a cam from Howard Cams. They put a hydraulic grind on it for me. The lifters I got I took a chance on, because I couldn't find a source for them, I got off of ebay. Knock on wood, so far I haven't to many problems with them. Tom Langdon had written an article, I believe in the 12PortNews,on how to put a relief on the lifter to keep them from rattling. I only did this on the lifter for 3rd & 4th cylinders. I wish I had done it to all of them now. Because I sometime have a little lifter noise. I heard that the new lifter that you buy now where re-designed and therefor the noise.
