K24 +RRC piston C.R?

Has anyone took the time to calculate the static C.R of a full K24 with a set of the Nippon RRC pistons? I've seen 2 different pages that claim 13.5:1 & 12.3:1, thats a big difference.. if noone has done the work to test this, I'll definitely get it done. I'd like to know 100% since I'll be tuning my own car. C.R is important information for getting the tune right. Anyone?

works well. Found the dome volume of the pistons offered or from the CR stated for the K20 to determine the dome volume.
Then switch over to k24 and enter that dome volume to calculate the CR. It is going to be higher than the corresponding K20 Cr with the same piston dome volume.
