It is shown that the combination of the Kobayashi-Maskawa CP-violation with the tree level $\\Delta S=2$ higgs exchange gives very large contribution to the CP-violating $\\epsilon$ parameter. It leads to the new strong constraint on the FCNC higgs mass, M>50- 100 TeV, enhanced by factor of the order $\\sqrt{m_t/m_c}$. Being addressed to the supersymmetric left-right models, FCNC problem requires both right-handed scale and supersymmetric mass parameters be heavier than 50 TeV for $tan\\beta\\sim 1$.
