The only way to read plugs when you are trying to jet is to do a run at the rpm in question, under load, do a throttle chop, and pull the plugs.

If you hear any pinging, back that timing off first, or get some better fuel. Pinging is a clue that you may have some detonation at higher rpm, but they are not the same thing. Detonation will ruin pistons and you will never hear it.
