This is from the number one cylinder but it's the most noticable, there is 3 like that, 2 more that lighter, and the rest look pretty normal...I have never seen them this color before.

You get that when you run octane booster... If you have not, I have no clue...

LOL before i fired up the engine for the first time i had a 1/4 tank of 87 octane, so i wouldn't blow the motor i added a bottle of OUTLAW octane booster to compensate for the octane, thanks for the quick reply, hey do I gapped the plugs to .40 per steve at powertrain, does this sound like a good gap for a N/A 331?

I would not be TOO worried about 10.2:1 comp. with alum. heads even with 91 octane.

Since I have fixed the tweecer issues I ran some 91 (didnt have enough to make it to the stations with 93) on a 10.5:1 iron head in 99* weather with no ping...although I was not giving it much timing either.

I guess you got your answer...I have never seen that before. But since you just put the motor together my guess was going to be some funky assembly lube burning off in the cylinders.
