This depends on what sorts of terms you want to change. The
bond,angle,dihedral terms are in ene.f. Electrostatics and Lennard-Jones
terms are scattered in many places (LJ are collected in short_ene.f).
Generalized Born terms are in egb.f. But be prepared for work: you might
want to consider something like Tinker, which was explicitly designed to
provide a platform for the sort of changes you seem to have in mind.
