Technical Twin plug head for side valve V8's

Hello, Just curious about this am considering to run this Ignition on my flathead .There are two ways 1 with the 2nd. plug next to the stock plug as per Flatfire or 1in the stock position and the second plug over the piston.Would the plug over the piston have to be fired after the plug over the exhaust valve. Thanks. Roger

 

sorry dont have anything but pics would be cool

 

I put mine in the center and fired it 1 degree after the plug by the exhaust valve. Sometimes I would shut off one or the other plug. Car was just as fast with one, the other or both.

 

Hey Rog, have a look at this, it may be of some help.....
