a good glow plug reamer would help, but replacing them all with pencils would help more.
if the motor has not been tuned recently, the valves would certainly benefit from the attention!

In the site I looked at it had Wires going from one Glow Plug to another but they appeared to be insulated.
On My Volvo the Pencil Type Glow Plugs were wired in Series Parallel. Meaning that all the terminal ends were connected in series to a Wire that has the Positive Voltage but the individual Glow Plugs are grounded in Parallel to the Cylinder Head.
(This is the same setup that people do when the install the Adapter Pencil Glow Plugs to replace the Filament/Loop type Glow Plugs.)
In that system one Plug can go bad and still not cut the electricity to the rest. But to test an individual Glow Plug you need to disconnect it from the Terminal Wire.
