when i am driving it will maintain the temperature it was at while at idle. It will not cool down. I am going to try a water pump next. I ordered a high volume one from summit. if this does not cure it off come the heads.
i guess its possible there is some sort of obstruction in the cooling system somewhere. Not sure if doing a coolant flush will help at all.
i used felpro head gaskets. What head gaskets is everyone using when swamping to aluminum heads?
