yes d-series pistons. B-series will not go right in

Like I said, the ZC(along with the USDM DOHC D series engine) has the highest head volume of all the d series engines, like wise it has pistons with the largest domes, so any other d series pistons are going to lower compression, Except for the GX(civics than run on natural gas) pistons I think those have an even larger dome. Call up Honda parts department, they should know.

Your only other option is shaving the head.
