Nope.  The B series head uses the same size as the A series.
Dunno where the idea of 7/16 x 20 came from.  7/16" is a pretty damn big
hole, actually.  FAR too large for an air injection nozzle on a
small-bore engine like an A or B series.

Yeah, the 7/16 - 20 X 1/2 is for the B-series head.

The ports on my head are 1/8 x 27 NPT.  Allen head plugs are available
at
your friendly local ACE hardware.
