Engine temp sensor fell off. Didnt notice it until I had run at 80MPH for Like 1/2 hour!! Replaced head gasket. 20 thousands taken off head. Replaced head gasket w/felpro composite gasket. Put her all back together w/ARP bolts. Still overheating like mad. Since I got her so HOT,:: angry :: Do you guys think I could have a cracked or warped block. Tks..........
