Forged pistons

I have done a lot of research over the past few days about this.

The barrier coatings do the wrong thing, they prevent the head, pistons, etc
from soaking up the heat like they should, and getting it out of the
combustion chamber. Results range from hotter EGT's, to less total timing
advance being available.

In a racing application where you have more than enough octane of known
quality I can see it. But on a street motor?
