I was wondering what spark plugs most of you guys were running in your A head N/A engines. What brand, heat range, projected tip or regular tip? Just curious,Thanks guys.

To me it depends upon whether the engine has a flat-top piston or domed piston.
AR3933 or AR3934 with a dome and AR3911 with a flat-top.
