706 heads coolant fix?
My aunt has a 4.8 silverado with the 706 heads and its using coolant. She took it to a shop and they did a pressure check on the coolant system for two hours and it didnt show a leak. But it's using coolant and smoking some too. What's the fix on these heads? Is it just head gaskets need to be replaced or the heads them selfs? I've seen issues with these heads but not fix. I have the same heads on the 5.3 I put in my truck with no problems.

I thought the same thing. I don't have a lot of info on the truck. She just recently told me about it. The truck is 100% stock 150,000 miles. I was behind her driving it the other day and didnt notice any smoke but she says it does smoke some.
