what exactly does this consist of and what are the benefits? thanks

 

makes the combustion chamber smaller, ie Higher compression. The drawbacks are the cams are retarded cus the head is shorter. nothing adj cam gears wont fix. and some people have head warpage problems when they deck too much off.

I've never heard flycutting to describe milling a head. I've heard of flycutting pistons to to make clearance for valves.

 

Milling also reduces quench area.

 

A fly cutter is a fancy drill bit that is used in a mill thats all. They are used to cut wide surfaces in small incriments.

Here is a link for a small one.

The ones that should be used to mill a head should be atleast as wide as the head so it wont have the risk of leaving a step if the mill is slightly out of tram.
