A thing or two more about the benefits of using anti seize
It helps keep the soft Aluminum bolt threads in good shape which is always a concern when dealing with the hard bolt threads and soft bolt hole threads.
Anytime you have different kinds of metal interacting with each other like the steel bolts and the Aluminum bolt holes ...........
You can get that white stuff that eats away at the soft Aluminum bolt hole threads.

The white stuff can also cause the bolt to become frozen and you may get snapped bolts, material around the bolt hole eaten away, and all kinds of other bad stuff you don't wanna see happen to your new shiny, pricey heads.
BTW, same kinda thing when dealing with the timing chain cover, water pump, intake, or any other Aluminum part.
