I had a 347 stroker built for my full size Bronco. It has Roush heads w/Hooker coated ceramic headers. The headers do not allow for room for full size spark plugs, so I have to run "shorties". I keep fouling them out. Anyone know what I can do?:banghead:

Try going up one heat range and see if this helps.

accel plugs for a 302 HO, sounds like the air to fuel mixture is off.
