Just follow the directions for installing an LS6 intake except for the FAST you have to replace the valley cover bolts with the ones supplied by fast. This is because the stock bolt heads are too tall and if you bolt down the fast then you risk cracking the floor of the manifold. Make sure you do the LS6 front coolant line and rear coolant plugs. My LS6 coolant line up front was actually a little too high to allow the FAST to go all the way down in place. I just tapped the line with a hammer a little bit to bend it down slightly and then the FAST fit on w/o a problem. Oh and I recommend putting the fuel line on the FAST before you install the manifold in the car.
