Near impossible without the correct tools.
With the correct tools I'd call it a 5-6 on a scale of 1-10 and time consuming.
You will need one of two tools to get it done, an on the car spring compressor or and off the car compressor which neccesitates pulling the head.
You can usually rent the old school off the car model and if it has a zillion miles on it you might want to just bite the bullet and pull the head and do it right. Clean it all up, get all of the crap and crud off of the piston faces, new plugs, valve adjust, fresh intake,exhaust, and head gaskets, new coolant. That baby would be ready for a trip to Alaska then. Make sure that the engine harness is up to being disturbed enough to do the head gasket though.
Otherwise you will have to bite the bullet and pay someone to do it. Doing valve seals is not something you do that often, even in a full blown shop. Truthfully I don't even have an on the car model in my shop.
