If you have a full-width half-max (FWHM) for your analysis, you can convert your z into a sig (-log10(p)*sign(z)), then run mri_surfcluster. You should give it a CSD file that corresponds to your FWHM, the sign of the contrast you are interested in, and the voxel-wise threshold. The CSD files are located here $FREESURFER_HOME/average/mult-comp-cor doug
