engine is a d16a6, i have gunk'd the hell outta the motor, scrubbed it, replaced the valve cover gasket, used crap loads of mega copper to make sure it seals... now i have noticing a puddle buildup between the exhaust header gasket and the head... what does this mean?

added- i have decided to get this engine rebuilt also.... anyone in the hampton area that is good, fast, and has cheap prices on rebuilds? i can get my own rebuild kit, i just need someone to do the work.. let me know~
