And fired it up! Ignition was instant, faster than ever before. And the exhaust pipe (sink drain pipe) that I put on quickly began to turn a nice shade of purple. I set the initial idle at 1400rpm and adjusted the idle fuel mix. Let it run for about half an hour at about half throttle and shut it down. Drained the oil again, inspected the magnet on the drain plug, and refilled with Mobil One full synthetic 10 w 30. Let it all fully cool down and re torqued the head bolts to 35 ft-lbs (what do you mean I have to take the fuel tank and fire wall off again!?).
Edit: I have since switched to Shell Rotella 30wt.
