Jun bolt on cams issue

[remcafee]

I recently rebuilt my cylinder head from accidentally downshifting from 2nd to 1st, bent all exhaust valves, so i rebuilt the cylinder head, oem valves, oem valve springs and ordered those jun bolt on cams to have a choppy yaris. i reshimmed all the cam followers to spec. timing chain is lined perfectly and go to start her up and all is good! it sounds beautiful with the cams! only 3 days later... i get multiple random misfires and have done every check possible. spark plugs, coils, rechecked timing chain alignment, and i dont know whats going on. car runs fine and pulls strong with cams, but its throwing misfire codes now when they are supposed to be stock evu compatible. anyone else running jun cams bolt on series with stock ecu?
