Agree 100% with Richard....regardless of what others tell you, do not try to re-use a cam and/or lifters. I have tried it a couple times, and had the same results as you did. It just isnt worth it....especially when you can buy a brand new cam and lifters for under 100 bucks. Now, you have to tear down your new re-build, because you undoubtedly have bearing damage and metal shavings thruout your engine.
