Leaking External Headbolts

[69cortezsilver]

Maybe someone can give me some good input, i have a 350 sbc, and noticed this weekend after drive antifreeze was coming up threw two headbolts..i took out 1 put teflon tape/permatex #2 on threads and re-torqed then did to second bolt, only to have worse leak on startup...Is this an easy fix? or am i pulling heads and replacing gaskets/new headbolts etc??
