Default NON OEM spark plug gap?

I'm gonna change my plugs from the factory installed ones to the NGK TR55.
Should they be gapped different than the factory high milage ones?
NO mods on motor, just time to change them, factory I believe gapped em at .060.

Also, any advice for the do it yourselfer? I'm capable of doing it, done them on my 3rd Gen but obviously the 4ths look to be a litle tougher. Any special tools I should buy or modify a certain tool to aid in this adventure?

those plugs should be gapped at .055 stock. I didn't bother adjusting that when I installed mine.
