It's overheating due to the fan not turning on. Have you checked the wiring to the coolant temp sensor? Maybe it was damaged or disconnected when you replaced gaskets. Also, check to make sure grounds and fuses are good.

I did check all that stuff it was fine I'll double check the wired though the reason it got real hot when I had it at idle was because the fan didn't come on but not cause it has a malfunction because my scanner was plugged in I don't know y the fan doesn't come on but it don't and I forgot. I also read something about some type of motor going out in the cluster on these car thanks for ur help and guidance

Motor in the cluster? Never heard of that. As far as the fan, are you sure it is good? Have you tried running power directly to it to see if it runs? Have you checked of there is power getting to it? Is there power to the fan relays?
