Is there a water port that runs through my intake from my cylinder heads, I have a 5.7 litre chevy pickup that has anti freeze on my intake were my gaskets are? The have been needed to be changed for a while now becouse of light oil seepage for the last two years or so, but now I have really green anti freeze there and its real noticable?The anti freeze runs the full lenght on both sides, now I know the one heater hose needs to be changed but it dont look like its leaking?

IT sounds like the intake gasket needs replaced. It is somewhat of a common problem with these engines.

Yes, there are 2 coolant ports going through the manifold and the intake gaskets are a very common cause of coolant leaks.
