With a 6.9 you can bore it out to a 7.3 and use 7.3 pistons.
With a 7.3 when you bore it you sleeve the cylinder back to a 7.3 standard piston.
Open circuit on the glow plug means it is burnt up.
Good glow plugs have about 1.5 ohms resistance on a good digital meter. Most analog meters will just show a dead short on good plugs.
The lifters are roller.
