Hello,
I'm going to be doing a tune-up tomorrow, and I figured I'd index my sparkplugs just for the hell of it.
As far as I can tell, the best place for the spark plug to be "facing" is upward toward the valves, and preferably toward the exhaust valve.
On the GT40-P heads, the spark plug is already more or less "aimed" at the exhaust valve, so should I index it so that my spark plug electrode is just facing "up" toward the valve springs, or perhaps up, and at a slight angle toward the exhaust valve?
Any recommendations?
Thanks!
