Just got my new Hi-Performance radiator installed friday, Truck is running almost 30 degrees cooler that it was. Received my new JBA ceramic coated headers this morning and Don't See any Torque Specs for the new bolts.

Anyone Know what the torque specs are for the exhaust manifold bolts?

 

As far as I know your engine should run the same temp as before. It however should stay that way once you start pulling stuff when before the engine would be running warmer than normal.

 

Well I towed to Death Valley this weekend and back to L.A. engine never got above 205 degrees. that used to be my normal operating tempurature. It used to hover at about 230 while towing.

Trans is still getting hot though.
