While I sympathize with your need for economy, I have to agree with the guys telling you to junk it. By the time you put new lifters, gaskets, and a lot of time and effort into it, the $60-$100 you save will look like peanuts. Especially if it wipes out in a week like every used cam I ever tried to re-use did. Then when you do buy a new one there's all the worry about what those grindings did to the rest of your engine. It just ain't worth it, man.
