Spark Plug ?

I run 291 and 351 autolights. Never had one foul. Even in a .140 bore by .150 stroke with a 380.
 
And instead of, "shorter compression height" would it be better to say; higher pin bore location?

Comments compliments criticisms and questions always welcome.
If the data does not support the theory, get a new theory.(Al Nunley)

And instead of "void of atmospheric pressure" would it be better to say "VACUUM"?
If the terminology doesn't support your "opinion", move to the right coast.
