Do Autolite #103 copper core (NON-platinum) plugs suck big time?

Will they put holes in my pistons, or just not last as long?

Will other Ford owners look down on me when they find out?

No, they will not put holes in your pistons. They will damage the cylinder less than any other plug but, won't last as long.

they're a common upgrade for the GM 3800 supercharged engines I know that. 103s and 104s are the most used.

The GM 3800 is supposedly one of thee finest pushrod engines ever made... not sure why that is... not sure if it will fit in my Ranger.
