There is one recommendation I would like to object to:
After liftoff, it is better to leave the throttle wide open instead of reducing to 25/2500 (done in order to 'save' the engine).
For noise abatement purposes, the prop can be brought back to 2500 RPM but leave the throttle wide open to top of climb. There is a fuel enrichment valve on most engines that will provide extra rich mixture for cooling purposes when throttle is wide open.
Having a JPI six-cylinder engine analyser (on a 231) it is easy to see that temperatures (CHT and EGT) go UP when reducing throttle during climb.
