With the aluminum case, might you still run into the head stud issues the mag cases had with spigot overbores?

Yessir, thats correct. Those big-bore engines must have twin-ignition to run on any pump gas.
The 100mm cylinders are just fine in the aluminum cases as long as they are properly prepped. Head studs do not pull; one simply uses the right ones for the job. We've had good results with the 993TT ones and thats what I recommend.
