Ceramic plug boot or short spark plug

Need Autolite AR25

I went with the regular copper 24's
I will go back with those if they foul out quick.
I went with the colder plug for a couple reasons, but, I think I would of been ok with the 25 after all and I might even try the 26's.

I'm going to do some 500 mile round trips pulling a trailer and I would rather be safe than sorry. I want to run not rich and I want to advance the timing within reason.

The old plugs were were useless to read as I found it retarded and rich. They were horribly sooty.

I bought a set
of the ceramic boot plug wires from summit racing.
I think accel makes them.
Not a big fan of their stuff these days but I was tired of headers melting my plugs in my small block mopar.
I also wrapped the wire in the heat wrap sleeve and an additional heat wrap conduit on the two wires that give me problems.
If this doesent work for me I’m gonna have to go with a set of doug’s headers to eliminate the problem.
