  We present an analysis of production and signature of neutral Higgs bosons on
the version of the 3-3-1 model containing heavy leptons at the Large Hadron
Collider (LHC). The production rate is found to be significant with a clear
signature ($\sqrt{s}=14$) TeV, showing that these scalars can be detected in
this accelerator. We also studied the possibility to identify them using their
respective branching ratios. Cross section are given for two collider energies,
$\sqrt{s} =$ 8 TeV and 14 TeV. Event rates and significances are discussed for
two possible values of integrated luminosity, 10 fb$^{-1}$ and 300 fb$^{-1}$.
