Car is running hot and i don't know why.

I had the same problem. I even went as far as to swap headgaskets and have my head decked. Still no dice. I swapped my head/block and it fixed the problem, so I think my problem was a clog in the head somewhere. Because the block looked fine as far as I could tell. I haven't gone through and looked at the head yet though. Oh, and by the way. The reason I got a new motor is because that problem got to the point where I could only drive literally half a mile after the car was warmed.
