A professional cam shop (you would have to mail it in) could rebuild your core to OEM. Or make it even better. Shop around for it. No affiliation to these, but just suggestions:

I only suggest it because maybe for $400 or less you could have a cam that'd give you more power or better mid-range or whatever characteristic(s) you prefer, for the same or less than a questionable used cam.
