I just installed the aluminum intake manifold this past spring. I choose to use blockoff plates even though the manifold has no crossover passage. The heat of the exhaust was sure to burn up my nice new intake manifold gasket and ultra black sealer without it. Also the nipple for the coolant hose to the heater at the passenger rear of the intake manifold is a smaller size on the aluminum manifold than on the cast iron one. I couldn't remove the old one anyway so a new smaller one was fine.

Also the rear A/C mount didn't line up with the drilled and tapped spot for it on the intake manifold. Otherwise everything went well.

Had to do the install twice however. First time tried to get by on one tube of ultrablack. Got an oil leak at the front of the manifold. Without the gaskets used in the front and the back, there is quite a gap to fill with sealant. Second time around used two tubes of Ultrablack and the manifold is oil tight still after 3,000 mi.
