390 fe lifter noise with misfire

Soooo I just assembled my 390.I rebuilt the bottem end but left the heads alone.It has a new Edelbrock cam and hydraulic lifters.Anyway I fired it up and it idles great without any valvetrain noise.But five minutes into the first drive it developed a wicked lifter noise WITH a misfire which I narrowed down to cylinder 1.After this at idle the miss and noise come and go.I reused all of the pushrods and were labeled so they returned to their original spots.Like I said before the heads were untouched except for a clean up and valve seals.
It only happens on #1!.
It has non-adjustable rockers and there doesnt seem to be any freeplay.
Ideas? thoughts?

I'm going to pull the valve cover off on Sunday and tear into it.
