oh shit...you know what i think they might have been. not severly loose but when i took it home they werent hard like they normally are.

I know how to tune and i know it couldnt have been overheated, because the temps were fine, it saounded good, and i have never fried an engine from being too lean. maybe the head bolts were loose enough to do this
