Heads are made out of a petroleum product, and therefore they react to heat like shrinkwrap, although it's very
subtle. That's why they seat instantly when the collar is warmed up after tightening the head down evenly. Guitar strings won't do that since they're not made out of a petroleum product.
So, you can either wait, or you can do it instantly. Both get the same results, except one is much faster. It's handy for when changing heads at a gig.
