Since you have Detroit cams, I'd pull the cover and inspect the cam and rockers. You have have scoring on the cam and/or a broken rocker. Or, your tensioner could have failed and not be keeping enough tension, or your chain jumped.
Since you've ensured it is not a plug or cop issue, and since the cams were replaced, the logical choice would be a mechanical issue there, assuming the alternator is producing 14 volts and you have adequate oil pressure.
