Okay, due to some poor advice from the guy at advanced auto, im pretty sure that I put the head gaskets on the wrong sides, if the left is the front of the car.. The look exactly the same though. My question is: what's the worst that would happen if I left them the way they are?? I know they say left and right for a reason, but they aligned perfect, and the only difference was one of the jacket holes was slightly bigger than the other one. I'm really hoping that I don't have to rip the engine apart again... Thanks in advance.
