Default EJ22 Ping?

193,000 miles, just baught it and owner put new plugs in.

At a little over 1/2 throttle - WOT from ~3800rpm and up i hear a very high pitched whistle that I believe could be more of a ping sound.

I have never really heard a car ping so its hard for me to say w/ confidence. Can anyone tell from my limited description if this could be likely?

I will check the plugs and the gaps and see if anything is suspect. What should they be gapped to?
