Quote: I could have sworn on the slant site they said face the opening towards the exhaust valve.
I know I smooth out the pocket where the plug is for flame travel towards the exhaust when I grind the chambers.
From what I have read indexing is worthless on the street, and mild race applications.
Cutting the ground strap might do something.
Don't know if I'd call it worthless, but it is well over-blown! The intake charge sure isn't taking the same path in to the combustion chamber at idle as it is at 6,000rpm.
