[Healeys] Cylinder Head Question

[Bob Spidell]

My BJ8 manual calls for 'Champion NY12' plugs (IIRC); no mention of 'ER.' 

Possible idea, though.

Just a thought .. spark plugs come in 'ER' - Extended Reach - designations, 
ie, the threaded portion of the plug is longer than 'normal' plugs .. Could 
these heads have been originally made for these "ER" plugs?
