My friend a machinist type just made me one of those. Maybe it would be ok for the smaller singles like a 7 or 8hp... I always thought head bolts were the way to go too. I'm always the over cautious type when it comes to such things. I would probably use a 6k rated chain and my 1 ton floor jack to lift it out then slowly lower it to my work surface.
 I've always done my best to avoid accidents instead of recovering from them.

think about it this way, torque on a plug is 18-22 ft lbs . an engine dress out is around 125 lbs. That means that one foot-pound of torque is a force of one pound applied one foot from the object's axis of rotation.

Made mine by welding a large washer to the spark plug, after knocking the porcelain off. Not my original idea; it came right from the SeaDoo manual. Rotax heads are aluminum.
Didn't use it on the K321, just lifted it out/in.

I wouldn't lift it the way either, I can see wayyyyy to man bad things that could very well happen. Heck I get nervous lifting mine with the bracket on the head bolt! Lol I have a piece of heavy log chain wrapped around the 12" I-beam that runs the center of our house then a come-a long that I attach to that to raise and lower an engine or whatever heavy object you want.

Just for laughs, I did some calculations (calculated by Engineers Edge and Matbase for shear strength) and it would take over 100,00 lbs to pull out the threads in 242 cast aluminum which is what air cooled heads are made of.

Lifting the KT or Magnum motors I use the tabs that are bolted on with the intake manifold bolts. If I can't winch them, I lift them with again...swift back jerking motion lol

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.

....... unless you want to buy a head. It's aluminum you know. You'll pull the threads right out of the head. Or crack it, or pull the whole thing apart, drop the engine, shatter the pan, bend up the tin-work, and then wonder why on earth you ever thought that was a good idea. Use the head bolts. Most engines have lift brackets on them. If not, a piece of angle iron with a hole drilled in both sides, using a head bolt in one hole, and the chain in the other is a much better idea.
