60G's and Duraterms are not enough difference to bother swapping out. Now if you need to then yes. I have ruined both kinds somehow so they are not indestructible. At least the duraterms quietly burn out - no drama. The last 60G's were only burnt off nubs left, but, the engine scuffed and burned through a piston. (Lots of either was involved to start it one last time to get it on the trailer so I am not really being fair.)
With over-advanced timing you can 'erode' the glowplugs. The plugs will have a rust like texture on them.
Regardless both self limiting brands require longer to heat up than the OEM unregulated glows.
