Custom Piston Machining

Im looking at this site and there are a few opinions of things that im not 100% sure about.

http://www.wiseco.com/PDFs/Cat...o.pdf

If you look at the bottom it says :
Ceramic Dome Coat
�� Skirt Coat - Moly / Xylan
�� Anodize / EN Plate
�� XLS Milling
�� Anti-Detonation Grooves
�� Pressure Seal Groove
�� Gas Port L / V / Both / Pres Eq. Groove

Im familiar with some of these things but could anyone go through them and explain the benefits and disadvantages of them

gas porting is a process of drilling tiny holes into the top of the piston so that the pressure created in the cylinder will help seal the rings even more.

shirt coating just reduces friction. and im pretty sure that the anodizing actually increases surface hardness by a couple points.

Gas porting is only used in drag motors right?
