Who here is good at reading spark plugs?

What heat range is it? What’s your compression ratio, car weight, gear ratio and converter stall speed if you have a converter?

I'll have to look up the heat range of the plugs. EDIT: heat range is 12. 10:5 CR. Car is light at around 3000 lbs give or take. I have aluminum heads, glass fenders and hood. 3:23 gear, 2400 stall.
