You missed the point of my post. The crankshaft does not cause the stroke to increase due to a rod bearing issue of any kind. What you refer to is "throwing a rod" meaning the crankshaft "threw" the rod away from the cap
as a result of a rod bolt failure , The excessive clearance lets the bearing rotate and then partially "nest" one half atop the other. Nowadays, "throwing a rod" can mean any connecting rod failure, breakage or otherwise.
Again, for this to happen,
a rod bolt has to fail or a bearing has to be worn through down into the shell the corresponding depth of the head gasket thickness plus deck height to allow the piston to hit the cylinder head and the plugs would still be untouched (extended tip plugs a maybe) none of which applies to the OP's motor.
