Too rich would be black smoke.

When you nail the throttle and blue/white smoke starts to make a trail it usually means bad valve seals.

white smoke is burning coolant... gray is oil... blueish hmmm... idk maybe he made it up lol since you beat him... check your coolant

so what would the coolant have to due with it, i heard if there's oil in the coolant then i have a bad head gasket. do you think this is whats up or bad valve seals

Chances are you may also be getting oil into your intake through the PCV. Adding an oil catch can could reduce that smoking.

Dont worry about it too much, Id bet thats exactly what happened. Gray smoke means youre burning some oil and blue smoke just means youre burning more oil and probably some carbon buildup too. Get a catch can and you probaby wont have that problem anymore, the pcv system on our ls1 is a little weak.
