ZCs, I'm scared of getting them these days. I'd love to run another ZC in my rex, but the quality ones just aren't really there anymore. I ordered one for my rex 3 years ago, and it lasted 2 months... I should have done a full rebuild on it.. it spun a rod bearing. My friends also bought one... it came with a previously broken t-belt and the mish-mash of valves that accompany a broken timing belt.
A mini-me would probably be nice, if you want the extra ~20hp and to spend the extra cash.
It sounds like you only need to replace the gaskets on the top of the cylinder head betwean the valve cover and head, along with the head gasket. My first rex had the same issues... it was still running great however. I have no clue how long it would have lasted. Replacing the gaskets would be the cheapest option.
