the top left one goes on the back of the intake manifold. the Center goes on the passenger back side of the head. the right one is the block off for the Carb`d manifolds.

You may also want to get http://www.toyotacatalog.net/M1WebGe...6-23409DA05DC0 to block off the crossover on the back of the head.

31.85 for the 3 plates that you need... or you can just buy the kit you linked to and leave the stock crossover on.
