Check the length difference between the short and regular plugs. On my plugs the difference was only 1/8" between the regular and shorty plug. DEI makes a decent insulator sleeve for covering the plug wire end. I also found Taylor makes the smallest plug boots. I finally ended up putting Lemons headers on to keep my plug wires from burning, but I haven't had them on long enough to know if they will burn the boots or not. The porcelain booted wires wouldn't fit my headers because they are a lot bigger than regular plug boots.
