Spark plug appearance

So I've been doing some work to get a truck on the road that came out of the woods (been sitting some time) and I pulled the plugs to check them and this is what I found... Any thoughts/concerns?

It's a 1995 F150 300 l6 5spd... A few different people had tried to get it running before me and had no luck, replaced the computer and BINGO! Now just doing the fine tuning.

Color is nice but that plug appears to have a comically long center electrode. What is the plug model number and what is the correct plug for an I6?

good eye !
your comment got me curious so i went to rock auto to check ... all the plug manufacturers have that long centre electrode for 94 and 95 I6 engines (didn't bother to check other years).

Looks good to me, too.

And yes, the I6 has an absurd looking plug- mine had some 'normal' looking plugs
in it and a pretty miserable cold misfire under load. The right
plugs, and it's running a lot better now...
