Spark Plug Question
1985 L98 (stock)
Had my plugs out the other day to check them, and I noticed that the plugs don't screw directly into the engine, that there are 'spacers' between them (I have no idea what they are or the right term for them).
It looks like a large nut, the sparkplug screws into that, instead of directly into the engine.
Were those spacers there from stock? What are they? Am I making any sense at all?!

They might be indexing spacers to ensure the pistons don't slap the electrodes...
Can you post a photo?

Okay, thanks for the help.
