Well it was quite a day,truck & trailer started rolling while loading, flat tire on the trailer,flat fender on trailer , busted sockets, busted knuckles,Scott almost drowned me but I'm pretty quick for a fat guy, but the short version goes like this, no steam cleaned piston's
, looks like a HG failure on driverside rear cylinder , pictures will be coming but not yet. The pass side did not want to come off it was well sealed , the driverside popped right off.

hate you had the issue, but atleast now you can see with your own eyes and are 100% sure now what it was. same thing that happened on my work truck, i don't guess the water was getting into the cyl. it was just building pressure in the res. bottle and exceeding the 16psi for the cap and spitting the coolant out. ha ha a damn head gasket check valve.
hope the rest goes well man.

The right head was very well attached to the block. Big boy was under there with a pry bar on the exhaust manifold trying to get it to pop loose. While this was going on I decided to give the the cherry picker one more pump, and of course it popped right off then.....well the water jackets were still full of water and Dave was directly underneath it......Surprisingly he came out from underneath with only a few sprinkles on one arm.
Never seen a 325lb guy move like a cheetah!!! It was pretty impressive.
Anyway...Like the man said there is no evidence of any coolant in or on any piston, and to be honest the one spot on the gasket that looks like it might have been leaking could be where it broke when the head came off. I'm pretty confidant that the rods have not been hydraulically shocked.
I appreciate all the input here. I'm going to order a set of studs in the morning, then go shopping for stock head gaskets.

That is curious if it wasn't dripping down the block, wasn't going into the exhaust or cylinders, where would it be going?

I'm sure there was some discussion as to who broke it loose.

You have to remember that cylinder pressures are FAR more than cooling system pressures. It is very easy to have combustion gases entering the coolant but no coolant entering the cylinder.
Scott if none of the pistons are clean or noticeably cleaner than the others you didn't have coolant going into the cylinder and therefore your rods should be fine. You can check top dead center height on all cylinder for comparison to put your mind at easy for rod issues assuming if there was a rod issue it would be bent and not as long as it used to be. Not sure what kind of variance would be acceptable but you will know a problem if you see it.

Yep. Already planned to do that very thing when I go over to clean parts.

Haven't done anything with them yet other than set them on the ground. I don't plan on tearing them down to get them fluxed or anything like that, but I will give them a thorough visual.
