Defender pressurizing the cooling system

Recently my Defender started overheating and losing coolant. Signs pointed to a blown head gasket or cracked head. I tore the engine down (enough to remove the heads anyway) and took them to the shop to be checked and reworked if they were ok. They were rebuilt and ground flat as there was a little warp(.05mm). Ordered all the gaskets and put everything back together.
Good news is that it runs fine. Bad news is it's pressurizing the cooling system somehow. With the cap off there's a lot of "agitation" in the coolant. With the cap on the top radiator hose gets rock hard before it comes close to getting hot. Any ideas of what could be causing this? I was meticulous about documenting how everything came apart but now I'm thinking maybe I did something wrong? Any help would be greatly appreciated. Thanks

You may have a liner problem, or you may have a warped deck surface on the block. Or you may have missed a problem with the heds or made an assembly error. I have a new article on dropped liners on page 12, here:

Thanks.

Thanks to all who responded. Confirms my fears. Looks like it's time to do more than just talk about converting to diesel.
