First Generation Firebird-L Mailing List ......................................................................... I just installed a set of AC Delco R44S plugs, following the advice of this excellent article on plugs and gapping by Jim Hand on the Classical pontiac website. I believe I got them at the local pep boys store.
http://www.classicfirebird.com/hand/jhand15.html http://www.classicfirebird.com/hand/jhand3.html " Gap the plugs to .035 for points and .045 to .050 for HEI. The .060 spec. for the early HEI was used in an attempt to ignite extremely lean fuel mixtures. It was soon learned that after about six months, the plug wires began to get dirty/oily and misfires were occurring because the wide spark plug gap was so difficult to fire. Use the heat range recommended for your engine or one heat range hotter. The heat range is an indication of how hot the plug electrode runs during operation. If it is too hot, the electrodes will wear prematurely, and pre-ignition could occur. If it is too cold, the electrodes will get a carbon/oil/crap buildup on them causing the spark to leak to ground instead of arcing across the electrodes as designed. The majority, if not all, of our Pontiacs are not run long enough or hard enough to warrant colder plugs."
