I tore the top of my engine off two weekends ago, had the heads checked and surfaced, replaced the headgaskets, etc. In the process I installed new wires and plugs. The Taylor wires worked like a charm, but the APP-764 sparkplugs did not. My SC would buck under a load. I finally replaced them with APP-2544s and she runs great. And yes, the 764s were gapped correctly.
