About a 6.7 litre Ford diesel V-8?

It was consuming coolant. And locking up, filling cylinders. First I replaced the EGR cooler, that was not the problem. Noticed there was coolant coming from the right side exhaust manifold. Took it apart, sent the heads to the Machine shop.
I put it back together, With new rocker arms, glow plugs, injection tubes, of course new gaskets, and damn it! It's doing the same thing again. Please don't tell me I screwed up the install, I have done quite a few before, Just not this engine. What else can the problem be?
