My heads a double plugged and the spark plug boot will not fit do to clearance problems on right side with stock push rod tubes. The orginal plug tip rested against the tube which I was using a spacer on so the threaded reach part of the plu8g would not extend into the combustion chamber on the right side (heads thinner on Right side where extra plug goes so the plug extends into the combustion chamber). So I went and found some shorter reach NGK's to put in there which gave me a 1/8" clearance. What I really need is a shorter electrode plugs to give me the clearance I need. Which means "maybe" with trimming the boot down I can get it on...don't really want to trim too much as I am afraid I will have an arching problem. So the next thought is narrower pushrod tubes. Figuring a more narrow diameter tube will help give me the clearance I need. Going to try dimpling the orginal tube but doubt I will get the clearance I need.
