Hi All,
I need new plugs, do I get B7ES or BP7ES??  I have found references for both??

The P signifies Protruding electrode, meaning the tip pokes down further into the cylinder than the non-P type.
On an un-modified engine (standard sized valves and cams) then either type should be fine.

Here's a pic of a B7ES and BP7ES to show the difference:

Many thanks Festy, just wanted to be sure the P'P' wasn't too long.
