Thanks to Eleanor, Gerard, Tassos, Bart H, and Phil Jeffrey.
The consensus is that a maximum search in a nearest neighbor
3x3x3 cube is the standard algorithm for peak search. 
Code examples suggested peakmax.f (ccp4) 
xdlmapman.f and xdlmapman_subs.f (Kleywegt cornucopia)
pksrch.f (Bill Fury's PHASES)
I have a feeling that with f90 array masking and maxval this
could be coded quite simply - 'let you know if I get somewhere.
Thx, BR
