Coolant lines are as follows:
1. Upper radiator hose from top driver side of radiator to inlet below throttle body. May be a two piece hose if you have a power steering cooler between the hose sections.
2. Lower radiator hose from passenger side of radiator to thermostat housing.
3. Overflow hose from radiator filler neck to overflow bottle.
4. Air bleed is two hoses: 1) from front of intake manifold (tube running between banks) to throttle body; and 2) from throttle body to passenger side of radiator. This is often bypassed to keep the hot coolant out of the throttle body.
5. Heater hoses are an assembly that run from behind the thermostat housing, bolt to the midrail, and then to the heater core located on the upper rear passenger side firewall.

sweet ty guys. Was waiting to put the intake on till I knew I had everything way in the back figured out.
One that im still not sure on is a line that looks SIMILAR to the one running to the driver side rear valve cover about a half inch soft hose?

That is the PCV it goes behind the intake to a Y then up the passenger side of the engine. Just replaced mine had to pull the intake for a bad knock sensor.
