[Mgb-v8] Spark Plugs for Rover V8

[Paul Hunt]

As far as the factory V8 goes it is Champion L92Y, Bosch W8DC or NGK BP5HS.
After having three Champions break the insulators when removing them for a
service check, the first I had broken in 30 years or so, I've never bought
them again.  These were the first I had seen with flat faces and sharp angles
to the ribs on the insulator in place of the usual rounded shape.  They all
cracked at a rib, and I suspect the sharp angles had something to do with it.

Roger Parker states for V8 conversions "Up to the SD1 they were the original
short-reach units, with later engines using the now standard long reach
versions, the same as any 'A' or 'B' series engine".

Spark Plugs quotes a whole series of GSP numbers by year and vehicle and
confirms the reach statement above.
