RB26 Spark plug question

[driver11324]

I had to pull the plugs while changing the timing belt on my RB and I noticed that they are really bright white after a couple hundred miles. I'm not sure if the iridiums read differently then regular spark plugs, but they seem a little too clean (lean/hot) than they should be. Is this normal?

You dont go off the center electrode. You go off the "Fire Ring". So that says you are running stupid Rich
