I'm going to do that, as well as see if I can route the tach signal wire as far away from any ignition component that I can. But it's kinda hard when you have the coil mounted in the stock location right next to the distributor.
I haven't found that to be an issue so far. I had initially thought the same thing, but then I completely lost a cylinder and found the culprit. Couple of 90 degree plug boots, and new wires, it was good as could be.
