Spark Plug Heat Shield Removal

im just curious about any long term ill effects on removing those spark plug heat shields on a 3.9 v6. im going to be installing the napa premium wires and just afraid off cooking the boots, thats all. Is it worth removing these things?

get yourself some pb blaster and soak overnight, it loosened up my trailer hitch ball that had been on for 3 years and the nut was rusted on pretty good.
