Whats up guys.

So I changed out my head gaskets and every other dam gasket above that with a kit and the bolts. Put it all back together and my car won't fire up anymore the way should normally. I've got it to turnover a couple of times but it was burnin something off I couldn't tell what it was when I looked in the the engine bay and then it stalled out on its own.
Everything is connected back the way it was so I'm not sure what the hell the problem is. Any advise?
