OS Twin plug head

[s.vannostrand at kodak.com]

The twin plug head in the Bully is designed so that each plug in normal to 
the hemi head.  This puts them on an angle, one in front, one in back. 
Adding a plug to a single plug head would have to be planned carefully 
because I'm not sure if there is room, and you don't want to change the 
compression ratio.

When done right, the idle is more reliable, and the transition is 
smoother.  Midrange is not as sensitive.  I have run my Bully with one 
plug burned out and can claim these improvements.  I don't experience 
lower idle, as is being claimed for these other heads.

The lighting procedure is simpler than you'd expect.  Light one and start 
the engine.  Run the engine at full throttle for a few seconds, and this 
lights the other.  You don't need to put the headlight on both.
