If you use the 2-piece housing its the same except the middle 2 ports on the diagram aren't there so those connections won't exist.

Also, in the replumb kit the 1" hose from the top of the manifolds to the exhaust dumps is long enough to go around the front of the manifolds and under them back to the dumps. 

Use the 2-piece housing, remove the old 6 port and remove the 2 fittings in the intake and put in pipe plugs.

Remove the old thermostat from the intake (2 piece thermostat comes with the thermostat installed.)

1" hose from thermostat to the bottom fittings on the manifolds, top fittings on the manifolds will go under the manifold and up to the fittings on the stainless dumps.
