No, that's no a problem. but if you didn't connect all the hoses from the valve cover breathers and idle air control valve properly, you'll mess up the a/f ratio.
All I see is a big fat red X so I can't see what you've done to confirm anything.
But like what others have said. Run at least 91 (a full tank) and see if the pinging stops or decreases. IF it does, then I suspect you are running lean and the increased octane is fighting the pinging off.
