The 964 is not unique... People have been using the case to lift the rear of air cooled 911's for decades and I can not recall reading anything about damage or a case separating or oil leaks. It's not impossible that something can happen, but the evidence over the years proves that there is no harm. In fact, case leaks are rare when compared to all the other leaks.
Instead of a hockey puck, I was told to use something that can form to the case and protect it like folded newspaper, paper bags, or heavy rags.
Some are skeptical about using wood across the front pan, but again, the proof is in the pudding and no damage has been reported.
I use the "Cactus Method" to lift mine. Named after someone who wrote up a DYI for lifting a 964/963 and it works perfectly... Especially if your car is lowered.

I lift my car from the engine case and use the Cactus method as well. The case is solid and has more than enough studs to hold it all together.
BTW: I can understand the reticence for a first timer, but 5 minutes watching a race crew with these cars will show you what works and they are experienced people.
Then why does owners manual say not to do it? I can see it being the quickest way to get the rear end up. I can also see it being difficult to trace any problem with engine to case lifts as there may be a subtle connection and not a concern for a race team who rebuilds the engine every season.
I did used the engine for a few lifts and hated every one. The mechanics just dont look right to me.
Let me ask you this, would you start the engine while car is lifted by case? Not me.
I am away from my car so don't have the owners manual in front of me. I do however have the workshop manual on my phone.
If we take that literally, if you can't use the jacking points to complete work then don't do the work.
The same manual shows the Porsche tool for supporting the 350kg engine and transmission assembly when removing it. It's the same point we are talking about here.
