Howdy-

The following datasets involved in this should all have the same grid/resolution:
+ the 4D dataset used to estimate the ACF parameters with 3dFWHMx
+ the mask dataset used for delimiting the brain in 3dFWHMx, and which will be provided to 3dClustSim
+ the statistics dataset that will have the clusterizing applied.

Perhaps, in theory, some of those probably *could* be on separate grids, because of the stability of resampling within AFNI:
[arxiv.org]
... but in practice, there is typically no reason to have any of those on a separate grid, and it would be *very* easy to mis-apply parameters or estimated quantities. If you are using afni_proc.py, all of the output dsets involved should be automatically on the same output grid anyways (I think...).
