Plug read, opinions needed

Are you indexing the plugs? I do that even on street stuff. Just apart of the laundry list of things I've picked up and incorporate. If not.. then reinstal plugs where they came from & mark with a paint pen where the open tang faces.
Yea read back a few posts. I do not index plugs. I will on some higher end race only stuff, our big cube small block Ford in our race truck for example, but I didn’t on this. It’s a thought I’ll consider at this point if we think it will make a difference.
