Maybe, that could explain why so many small block Chevy cams went flat all through the '70s and 80's. It's also a possibility that a cam vendor had problems with quality control that caused a lot of problems. Seems to me that some Ford engines in the late '50's and early '60's had a bunch of issues like that, too. I think it was with the onset of the FE engine and the MEL engine, 352,390,430's, etc.
