Is it hitting the floor board? If so then your getting knock, as for pinging I have no idea. Did you check the easy stuff, like plug wires and the clip to plug up the coil packs? What about the wire to the coil pack itself?

I ran real lean after headers and Y, around 14 to 1 accordign the the dyno wideband. so I would say yes, that could happen.
