No the intake is not installed just placed on top and, yes the fuel rails and crossover need to be moved around. It was 5 am and I just water to see the intake sitting on top. The timing cover and water pump are not the ones I'm using but my edelbrock ls2 2 peice cover had to be machined to clear the meiling oil pump. I used the old ones to seal it up for now. I'm thinking about a Flowkooler water pump any suggestions?
