Changing spark plugs in a small block 360 Any recommendations on which brands are the best to use?

Just an aside- Splitfires used to be made down the road from me.....by hand!

I stumbled into the "factory" one day circa 1990 while looking for an electrical supply store for a side job I had.

It was about a 25x25 storage warehouse type unit with a custom grinding jig in one corner.

There was a pallet of plugs in the center of the room.

They were special order "no logo" Autolites.

The one person in the room explained to me what he was doing and what the theory was.

I thought it sounded pretty cool.
