Val, One more thing not mentioned yet.
Do not rely solely on the lifting eye on the head to hoist the engine. There are past accounts of cracked heads from exerting all of the force on this area. It seems the plan would be to use webbing slings...I would rig these to a single point to take 95% of the load (tied to themselves around the front and back of the engine so it they can't slide together...the engine mounts should keep them from sliding apart), and then I'd still have a strong point as a backup connected to the lifting eye for the last 5% and to handle any tipping loads (in case of sling failure or movement too.)
On our C-30's, getting the slings around the engine will be tough, but not too bad...you should be able to get a couple of slings under the oil pan just in front of the aft motor mount. As the engine comes up out of the box, you can secure the anti-slip straps around the flywheel & tailshaft area while everything is stable.
The main halyard should be attached mid-boom, at the same point as the lifting tackle, to support the middle of the boom..however, the C-30's telephone pole mast & boom should easily tackle this job without much help..the main halyard is really backing up the boom topping lift on our boats...and preventers to control boom swing are a great idea!
If you get lucky you can get the boat next to a bulkhead and swing the motor right into a truck or dolly, etc.!
Oh...and if you do this in the water (which involves much less up & down distance), don't forget to secure the prop shaft inside the boat..like a couple good hose clamps or something until the boat is on the hard..I would not trust the coupling to hold it, although in reality, you'll likely have to press the coupling off the shaft if your boat is anything like mine.
