Howdy 914World

I am in the process of reassembling my car and decided to go ahead and mount the clutch and pressure plate to the flywheel. I've only done this a couple of times before on VW beetles, so not a whole bunch of experience here but seems pretty straight forward.

When I mated everything up together, I noticed there was quite a bit of gap between the pressure plate ears and the flywheel mating surface (probably .25" or so). But, I figure this may be normal and the ears cinch up when you go to tighten the PP down.

However, I did run into an issue when snugging everything up. There doesn't appear to be enough clearance around the PP to use regular hex head bolts. IE: the socket can't fit on the bolt head. Also, by the time I got them as far tightened as I could, the heads were at or below the level of the starter ring. Is this normal? Should I be using allen head bolts here for the clearance?

I read on this post about machining clearances out of concern that perhaps my flywheel was machined improperly. On that diagram, my "A" measures 21.60MM which would appear to be out of spec.

Here are some pics of the situation:

What do you guys think? Is this normal / do I need allen head bolts? Or, is something strange going on here.
