Had cam covers failed before? Had it been driven with oil in plugs? Its possible you've cooked the HT lead.

I'd do a paperclip/pedal test see which pot is miss-firing. Transfer HT leads, see if fault moves. If not could be DIS pack.

Did you use genuine gaskets?

Random miss, and it must be a DBW, so would give individual cylinder codes as well...
