The Continental IO-360 in the Cirrus is more likely to suffer cylinder distortion (barrel shaped cylinders) or valve seat problems than things like cylinder cracking. You wont really know if there is an issue from LOP or shock cooling until one day the LAME says the compression's are low and pulls a pot. In my experience the danger zone for this is 800 - 1200 hours.
The guys that do most dyne & analysis work on the Continental IO-360 are ....Continental! Read the engine operators manual.
I would have thought you could put a lot of fruit into the panel of a low time Archer II for the same money as an SR20
