I had recently(yesterday) put a ls stock motor in my integra (92) and I drove it not even 2 miles and temperature started to rise just over halfway then when it leaned more at 3/4th so i killed engine when I did I looked back while coasting and I have never saw so much white smoke in my life, then every since then, have been smoking white like unbeleivably bad, I think it is the head gasket....and other suggestions?

I have another LS head...
So if this was the case, I hear that the LS comes with a metal head gaskey unlike some other models that is re-usable?

Any help wont hurt....
