I absolutely agree with Crankster's post about the high dielectric grease around the inside of the rubber boots. Not only does it allow them to slip on the tower sockets more easily, but it also allows air to escape from inside the tower socket. The best scenario would be if you could achieve a vacuum in there.
Also, around here (since we have high humidity and drastic temperature changes in the early morning and evening, I discovered decades ago that the condensation created by these temperature differentials was causing my tower sockets in the dizzy cap to corrode (the copper turns green) and causing the engine to misfire. So I took the dizzy cap off, filled the tower sockets with a tarnish remover, and once they had become clean, I dumped it out, washed and dried the tower sockets carefully, then I got a Q-tip and dipped it in high-dielectric silicone grease and smeared the Q-tip all around inside the tower sockets.
Never had a misfire again from corroded tower sockets.
