Don appreciate your input and all these things have been replaced along with doing a chemical flush which showed no blockage. Also set the timing and the advanced timing had a leak so replaced that p[art as well.After all this ran the car 20min and temp jumped to 248. We did do a pressure check on the #1 and 2 cylinders and I have attached the readings which does not look good. Also attached a picture of the 3 plugs we pulled. Don't know that we have much choice at this point but pull the heads unless there is something we missed. The engine has also weakened and not running strong at all anymore. That's where we are at right now. Thanks.
