60 series Detroit with fuel in the coolant due to bad injector cups. On this year of 60 the head has to come off to replace cups so it got a new cylinder head since the engine has 700,000 miles on it. Adjusted the valves and Jake’s, flush the cooling system and a few other things. Fired up and runs great.
