So, due to a landing incident that bent the props on my 360, an engine tear-down is now requried.  This particular engine has approximately 900 hours TTSN.  New props will probably be needed also.

I need some feedback please. 

Engine:
  - install high-compression pistons now? Which ones?
  - get the engine overhauled now? Zero timed?

Prop
  - I had the 72" Hartzell props
  - should I go for the newer 68" ones?
  - Scimitars blades?
Rick,
 
Everything you asked - depends.....................
 
When I had my engine torn down after a gear up landing, many of the decisions were made easy.  I had 400 hours on Cermi-Chrome cylinders that had just started to exhibit increasing oil consumption (a known problem), so I had the cylinders replaced with ECI Cermi-Nil cylinders.  My crankshaft was just a wee bit bent so I had it replaced with a heavier one (engine rebuilder gave me trade-in credit).  The cam lobes had not been wearing well so I had them replaced with 1-piece cams.  9:1 pistons were obtained to replace the old ones.  I was able to retain the prop hub and the blades were replaced.  Have you considered an Aerocomposite prop?  I had the fuel system rebuilt also.
