Hi Daniel
I am running the Pierce head on my Midget.  The spark plug I am running is a 
NGK DCPR6E.
I went on the cheap with this rebuild and only have low compression pistons, 
60 over, at 8.5:1.  It seems the engine wants and can handle much higher 
compression than that.
I had the head from a parts barter, so that is why I used it.  In the 
current state of  tune, my seat of the pants dynometer says I lost torque, 
but gained high rpm hp as compared to a stock engine I removed.
YMMV.
