2000 Honda Civic Refurbished head making knocking noise

I recently had two bent valves replaced and my head re-decked. I have a D16Y8 honda v-tec engine. All 16 seals were replaced when the head was torn apart. Once I put the head back on it instantly started making a knocking noise. This noise is quieter than the knock from the bent valves. I double checked the lash before starting it up. Everything was lubed before installation. What could the noise be from? It is a consistent noise whether the car is idling or revving up. Definitlely coming from inside the head, it sounds like the #2 piston valves.
