360 LA installing Promaxx Aluminum heads

I re-calibrated the O2 sensor this morning and tooled the heap around town.. got some gas. Numbers did not move even a little as far as I can tell. Wondering if the sensor is just FUBAR at this point. But it is consistent across the band... always shows fatter than the plugs show and exhaust smells like. Running fantastic at this point. I'm going to leave it as is for the rest of the week... too much knob dickin I'll likely screw the pooch somehow and never get the tune back to where it is right now. If the plugs come out in a few days looking like they do now.... I'm gonna call it done and get to work getting the new fiberglass hood fitted.

To be continued...
