Well, i got the truck to cool down. It still is running warm, but not overheating. Under heavy load (going up a good sized hill on the freeway after its good and warmed up) it will get to the "L" on "normal", but then cools right back down once i crest the hill. Still want to replace the heads, I know that shipping from KY would be cheaper than Canada, so John, I would love to get those heads. If you would rather keep them, then Andrew, I would gladly take yours off your hands. Thank you two so much for offering the help. If there is anything you guys need, let me know, and i will try my best to help you guys out.
