I just finished rebuilding the top end of my 1600 dunebuggy motor. I put on CB preformance 044 heads 40x35.5mm. I have 87mm pistons, and a 1.25 Scat rocker arm. I also changed to electronic ignition (dorp in), and Kadron dual 40 carbs. Everything else stayed stock. I know the heads have the smaller hole for the sparkplugs (12mm?). What type of sparkplug do I need? Thanks for ANY help, this is my first major adventure on the engine side. It has been a blast, but I constantly hit walls that are slightly harder than expected. I think it will be worth it Thanks, Terence Painter Texas Manx Club
