    From GM performance parts:
    Any small block engine, regardless of year, that uses Vortec heads, will require an external coolant bypass line from the intake manifold to the 5/8" hose nipple on the water pump (passenger’s side). Suggested routing is from the 3/8 NPSF boss on intake manifold to the water pump.

    What intake are you using? It sounds like your gonna need the bypass hose. Read through the beginning of this post. Lots of info
