How are the oil temps when you do runs like this??
Your timing sounds like it's off, You can't really base your ign off the stock dist curve well you can but your twin plug now, probably with different cams, intake, everything. If i were you i would pull some more timing and make a run and see if it runs better, if not start by adding a degree at a time and working your way up. I would also fatten up your afr to give you a little more wiggle room. Then after you get the car to run clean , then you can go back clean up the air fuel. After it runs clean i would really hit a dyno beause wht power the engine is making will tell you everything. I've tuned two exact same engines, i built them, everything was the same, one engine took more 10 degrees to get to MBT. Also don't forget to read your plugs WB meters are great but the plugs and tell all if read correctly.
