Yeah as I mentioned above I will be getting the intake manifold as well. I was told I need a bigger heater hose too? The heads are complete, but they don't come with valve covers??? Where can I pick up some valve covers cheap? And people keep saying something about having to relocate a thermostat or something from the old intake onto the new one? Drill a hole???? CONFUSED ON THAT ONE???? The intake manifold is off an 03 but dosn't have the ALUMINUM crossover, is that bad?
