Disclaimer- This is not an A-body, but it's a big block Mopar (72 Roadrunner with a 400/727.... close enough? Hope so. It's really bumming me out.

I guess I'll start this one from the beginning. I was driving my Roadrunner one night around 10:00pm and came to a light on the highway next to my house. I took off (perhaps slightly motivated to accelerate a bit hard per the turbo Grand National next to me) and upon driving about a half mile and glancing down, I saw my temperature gauge rising... I eased off the throttle and took the first exit ramp. The gauge wasn't quite pegged (close) so I decided to limp it home (~1 mile) barely pushing on the gas. I turned onto my street and could smell the coolant so I decided to shut her off and open the hood. Mind you, the gauge was indeed pegged by now.

Besides the coolant pissing out the overflow, I could see what remained of my water pump belt tangled in the fan... I was not happy. Anyways, we pushed her home, changed the belt, and she ran great.

I kept driving her (it's been about two years) but continued to notice a small leak coming from the engine. It's been getting a little worse over time and tonight I tried to diagnose it. It looks like (based on the trail of grime) that the passenger side cylinder head is leaking coolant towards the rear. There is also a small leak looking like it is coming from the drivers side.


I want to make it clear that there is no coolant in the oil or oil in the coolant. I have changed both and they are both clean. It is my thinking that the overheating caused one of the following:
1- The head lifted slightly and is allowing coolant to seep out under the head gasket, but the cylinder is still sealed.
2- The sealant on the exhaust manifold studs came loose when it overheated and every time it gets warm, the coolant pisses out the stud.

Anyways, any thought/comments would be appreciated. I thinking I might have to pull the exhaust manifolds and re-seal the studs. Am I missing anything?

The first photos are of the drivers side, and the last two are of the passengers side (I'm sure most of you could figure that out... just wanted to clarify).
Thanks all. I really appreciate it.
