To answer my own question before I post it, I think cost is the reason.
The 2011 Ford Shelby GT500 engine is over 100 pounds lighter than the 2010 GT500 engine. Why? Ford used a process where the steel liner is actually heated and sprayed onto the cylinder walls on the 2011. The 2010 had steel sleeves. So why not do this for a model engine?

Last I looked HVOF and/or Praxair "D" gun Metal/Plasma spray is limited to bores that are 2 inches or larger. I know nothing of the process Ford uses.

Sorry HVOF = High Velocity Oxy-Flame
