I'd be happy with a 2.2% gain... No way they're worth 22%.

If you want to do it, I just use a Sharpie to mark the electrode position, and a set of Moroso Indexing Washers - they come in 3 different thicknesses that allow you to move the electrode position in approximately 60 degree increments.

thanks in witch direction would you have them pointing and at what time like 10 and 12 or what ever it is?

I always was taught to point the gap as close as you could to the center of the exhaust valve.

If you are careful, you can use those Moroso washers a number of times.

I index the plugs in all my motors. Every little bit helps.

I am not questioning you but why to the C/L of the exhaust valve and not toward the intake.
Would it be for issues of the f-a mixture hitting the plug from the side vs the front????

We always indexed to miss the piston, lol.

Outside of that id just put 'em at 12.

I think it's just a target point to ensure the gap is open toward the chamber.
