Stopping the knock: Lower compression and ported heads...

I was able to drive the car today. Good news...NO detonation at all. I'm running a mix of about 90% 91 octane with what 110 leaded was left in the tank since before the teardown. It was also only 50 degrees out.
I still think that with 91 octane at 100 degrees I should be fine. There are still a few details to work on though. It feels a bit rougher at idle and the idle vacuum is certainly lower. I may need more initial timing. I'll probably need to go with smaller jets since I'm running in the 12.0 to 12.8 range at part throttle. (According to the Air/Fuel guage) Power feels pretty good but the secondaries don't seem to be opening fully. It doesn't seem as loud at WOT as before.
With work taking up as much time as it has, it is hard to get as much done on the car as before. I was unemployed from March to early September so I was able to get much more done back then.
