Those pistons will have about -5 cc and 1.560 height.
Dont always believe everything they claim in ads especially compression ratios you have all the dimensions of your engine combination plug those into the compression ratio formula.

Very Important: You said or claim that your block has been resurfaced you have to measure how far down in the hole your existing pistons are at TDC. This easy to do no fancy gauges are needed. Find a flat piece of metal like a ruler or something and some feeler gauges, rotate till piston is at top of stroke and start testing which feeler gauge will fit. Measure in line with pin that way piston rocking in bore will have very little effect on your measurement.
If you dont get this done its just a gamble if youll have a problem with piston protrusion.
