^ the 2 posts above tell you.
theres a coolant line that runs from each head front and back and connects under the intake. you can get the coolant line kit from a 01-02 which has the plugs in the back and just a crossover.
i cut it out of there. plugged the front tube going back, and when i cut the rear two i left about 2inches of tube and just connected the rear 2 with a rubber hose...works good...
allen head bolts on the valley cover...or you will crack the intake manifold.
everything else just transfers over from your stock intake...
also-there is a sensor on the engine back of the intake on the drivers side. sticks straight up. be careful, that is the oil pressure sending unit. easily broken.
take the rubber vacuum line off the brake booster and work it out of the back around that sensor....
easy swap youll be suprised...
