Charles,
when I assembled my Ulster engine back in the early 1990s I fitted HT cap screws (like the one in your photo) in place of the majority of block studs. There were a couple I couldn't replace because of casting restrictions. I modified the underside of the case to accept the bolt head face flat and screwed them up from the inside.
The car is unsupercharged but has taken near enough 100000 miles of hard use and abuse (especially early on) since then without issue. I would certainly consider this modification in again, if I was building a potentially spirited engine.
