So my father brough his pride and joy to me and it would not turn on after over heating on the hwy. I noticed a puddle of coolant in the exhaust header. So I knew the headgasket probably has been blown.
I began tearing down the engine (first time ever working on these 603 engines, im more a smallblock Chevy guy). I managed to tear it down and get the cylinder head removed and dont really have conclusive evidence to show the headgasket was blown, the gasket looks solid and one piece. however the #2 cylinder is full of coolant, not sure how it got there, will have to really analyze the head to make sure there are no internal cracks in it thats allowing the coolant to escape into the intake chamber. Im going to take the head to a machine shop to get a resurface/cleaning job done and see if he finds anything wrong with it. Then I will put it back together.
BTW using the rail pin puller is so easy, took me 1min a piece.
Here are the pictures for those who are interested.
