I replaced my head gaskets 8 months ago or 15,000 miles on my 2003 LB7 and I am now having similar symptoms. Heater blows cold when Idling, coolant system stays Pressurized.
I replaced all gaskets and Head Bolts, Water Pump, coolant.
It is programmed at 90 hp above stock and I do run EGT's up to 1600 degrees.
Stock Exhaust, Stock air Intake. ????
What am I missing for this to have happened again?
If I do them again what would you recommend?
