I pulled with my truck last weekend and at the end of each run the truck pushed a small amount of steam from the overflow. I'm assuming this means at least one of my headgaskets are on the way out. I don't have any issue with it burning coolant at the dragstrip or daily driving. Basically I'm curious to know if there is any risk to continuing running the stock gaskets until they become a bigger problem or could that risk other parts? Also what are people normally paying for labor to do studs?
