It turns out that it isn't just the gear on the end of the starter which pos out to engage with the ring gear, most of the end of the starter comes with it!

So, while the starter was engaged, the studs would whack straight into it and the flywheel do no more than 1/6 of a rotation.
Plan A was re-hashed to become plan C and required some more extreme flywheel modification. The studs which we had inserted were removed with great difficulty. The Loctite we used had "Extra Strong" or something along those lines written on the bottle. It was amazing, the studs were locked solid after only an hour ror two! So much so that 2 of them broke off when trying to get them out!
My friend set the flywheel up in his lathe and cut down all of the ribs from around the outer edge, then fitted new studs in the old holes and turned them down to the appropriate size.
Here's how it was before:

Now the flywheel is re-attached, the RPM sensor located appropriately and the engine runs suspended from the engine crane! It's a bit cold, and smoky as a reslt, but works fine.
I don't know how to embed a video, but you can see the startup on youtube here.
To say that I'm a happy camper would be an understatement! So, now on with the rest of the work: making engine mounting brackets, making clutch pedal assembly, adapting drive shaft, etc...

Well, plan B turned out to be a bit of a disaster! I attached the modified flywheel to the engine, and after setting the height of the RPM sensor so that my newly attached studs didn't hit it, we hooked up fuel and sealed up the oil & water pipes after a emptying a can of water in and seeing it flow across the floor! My self and a friend hoisted the engine up on the engine crane, hooked up a battery and hit ths starter. There was the usual click of the starter followed very closely by a thump, and the engine was locked solid!
