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 ?
