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?

blow out the spark plug n shield with compressed air, remove the spark plug, grab the shield with some good size pliers and give it a wiggle or tap with a hammer and it should come off, these things are nothing but a problem as they hold grit n dirt around the sprak plugs and when the plugs are removed the crap can fall into the engine and cause pre-mature wear problems
