Except, I only notice mine "pinging" in gears other than Park or Neutral. Am I missing something here Just put new heads on, so no carbon. Maybe a bad fuel injector???

Detonation will not occur without load. More info would be required. That said, low octane, a large vac leak, a MAF issue, running lean for other reasons, and about 20 other things could lead to detonation.

Click to expand... My timing is between 10-12*, so I run 87 octane. The engine was just put back together w/ new gaskets/seals. The MAF is stock but I check it regularly for cleanliness. I did pull my plugs, and #'s 3 & 7 were bright white. Usually means a lean condition. I am going to buy new plug wires and a fuel filter. Try some "cheap" and easy things first, then go from there.
