engine overheating

engine started overheaing about a month ago and cant figure out the problem. Have changed the thermostat about 5 times and then changed the fan clutch, fan, radiator, waterpump, hoses and flushed the cooling system. Still overheating. Pulled the heads and on the right bank between the #6 and #7 pistons the gasket wasn't sealed like it was suppost to and had dirt build-up between the two. Had the heads machined, valves clean and ground and changed all gaskets and put back together. Car ran fine for about two days and started overheating again same problem. ANY help would be appricated.[img]/phpBB/images/smiles/icon_confused.gif[/img][img]/phpBB/images/smiles/icon_cry.gif[/img]

prolly need to deck the block.?

How is your fuel system? It could be running too lean.

Do you know that the runners in the radiator are open and flow freely? Had the Rad boiled out lately? Also, a Radiator cap that leaks pressure will run the temp up. Replace the cap to hold pressure and try again.
