Solid cam damage diagnosis help

If Dave had ANY balls, he’d have the OP send the cam to him and he would have verified that it was incorrectly ground, and the HE would deal with HIS subcontractor. And he would make the OP whole, which never happens but at least he could have refunded his money for the junk cam and maybe some money for gaskets and such.
Yes 1000%. I have never bought from Hughes, but checked out their cams for a 383 build. That said, I have read more than 1 unhappy review of their service on the car forums I visit.
