You sure they aren't 'semi surface gap plugs' ?  In the industry, semi
surface gap plugs look almost identical to surface gap plugs, except
that the bottom of the shell has 4 notches in it, creating 4 ground
electrodes in the shell, and these plugs are slightly hotter than
regular surface gaps, but not by much.   They are used in some of the
new Mazda Rotary engines, but they could have been used in the Alfa
too..
