With the 59-58cc I would have to lean towards, no. Unless of course you were willing to flycut then sure. Or if you are already running a forged reliefed piston. But yes, it will up your CR probably to about 11.1'ish. 93 octane all the way from there!

I just ordered a set of PRC 5.3 heads and Torquer v3 (.643 intake lift) from TSP. I had them mill the heads as much as possible while leaving adequate PTV clearance. They said they should be able to get down to around 60 cc chambers (.015 - .020 milled).
