Flatheads breaking off engine stands and falling.

[Jay in Mass]

I'm just wondering if someone has some pictures of flatheads where the bellhousing area broke off while they were bolted to an engine stand. Some say that it is OK to do it to the 49 - 53 engines.
Just need to show someone the pics because they think that it is an old wives tale. (I don't) In the past somewhere, I've seen pics of finished engines that crashed to the ground and the nice new heads and intakes got destroyed.
FWIW, I use the one that bolts to the exhaust manifold bolts.
Thank You
