My engine will be completely rebuilt with a perfectly balanced and new flywheel, also new clutch etc, T10 also rebuilt, I suppose the risc of parts flying around is not that high?

Not cast iron, high strength steel. Cast iron is too brittle to contain fast moving shrapnel; think of holes poked in iron blocks by connecting rods or other pieces of a failed engine.
Original COBRA lettered five and six bolt units are high strength steel castings and I have seen them complete contain a 9,000+ rpm failure inside of them.
There were also pressed steel aftermarket models but not all will fit an original car's chassis without modification. If one starts cutting, grinding, or heating and beating on one to make it fit they lose a lot of the strength and integrity you wanted one for in the first place.
Even brand new stuff can fail and there is always a small fraction of defects in all manufactured things.
