Hi guys ,
I have a pair of Hedman headers installed on my 85 . They went in pretty well, but there in an issue with the close gap between the spark plug and the wrapped header .
Recently seen some sparks ( arcing ) between the spark plug cap and cylinder . To me , the only solution seems to be a shorter spark plug and a better insulated spark plug wire set.
I've bought a set of new wires from Zip and those aren't much improvement over the old ones I had .
Is there someone who is using such short spark plugs ?
Any recommendations ? PN# 's ?

Thanks !!!

I have the Accel header spark plugs, part # 8199, in my 89 with Hedman Elite's
Also have insulating sleeve over each of the spark plug boots.

Do these Accels also work for the iron heads on my 85 ? Sorry for the dumb question ....
Seen on Summit Racing that they are listed only for 86/87.

I had issues with the Champion , the Accel work well.

But my 85 's engine is worked.

I also use DEI Spark Plug Boots they help.
