Dynamic compression is the number you should be concerned with rather than static.
And, like others have already stated, unless you have actually measured all the components you are theorizing the results. Measure the volume of the chambers, deck height, valve reliefs, etc. to get exact numbers to calculate the compression ratio. Plugging in numbers obtained from a spec sheet gives you the compression ratio of the engine from the spec sheet, not yours. I measured everything the last time I disassembled an engine and not one measurement was close to spec.
Remember, cylinder pressure is key. The higher the pressure the more chance of detonation. Compression does not start until the intake valve closes, knowing exactly when, in terms of degrees before or after bdc, the valve closes is paramount in determining the dynamic compression ratio.
Your choice of camshaft no only determines the dynamic CR but also the rpm at which you will obtain peak power. I use a camshaft with a duration at 50 of 230-236, if I replaced the shaft with a duration of 236-240 the dynamic CR would be lower but the rpm at which I would obtain peak power would be higher. I would also expect a higher overall HP value and the torque value would lessen.
Good quench helps to reduce detonation. I've never used Icon pistons but the ones shown above look like they have a good quench pad as well as a nice dish to reduce pressure.
Just my thoughts, I'm not an expert.
