Talking with Tony at Dirty Dingo, he referenced the article at:

Some LT4 supercharged models use a vent from the oil pan to a baffle box mounted behind the water pump.
You will have to modify the steel line. You can cut both ends and attach a rubber hose between the ends.
This will allow an aftermarket engine mount.
So, yep, need to modify the vent tube (which is what I mentioned yesterday).
Also, it seems they are recommending that I use the Energy Suspension motor mounts.
#3.1114 has a zinc finish
#3.1115 has a chrome finish
Looking at these, they have a plate that is supposed to go between the engine and the mount that has the same raised area:

So, I think I'm going to simply take the grinder to the mounts I already have and remove the raised area, as recommended in the book "LS Swaps – How to swap GM LS engines into almost anything".
