I don't know anything about the Pertronix directions. I only have my
Uncle's anecdotal evidence of what worked for him and he told me he is
running a bigger gap on his plugs now. Obviously, your results may
vary. I don't know if he swapped out his coil either. He's pretty
"frugal", so he probably just put in the ignitor module only. I do know
on my 1978 MGB the stock plug gap is .035 inches. Of course, that is
with the stock Lucas 45DE distributor and electronic "Opus" ignition. I
now have an after market Piranha (IR optical) ignition installed by a
PO. It all seems to be working for the moment.
Keeping my fingers crossed,

The Pertronix alone does not constitute a re-gap to a larger setting.
Without a hotter coil
you won't get the extra voltage needed to jump the gap. Also
remember....the higher the compression, the harder it is to jump the
I've never 'adjusted' the clearance on any of my four current LBCs
running the modules. I just bolted them in. I've never had a problem.
