Kewl! I got pretty good at yonking the intake off during my rebuild. You missed a prime time opp to block off the EGR however(unless you dont want to).
I couldnt leave well enough alone, so since my Z is in the shop, I pulled the intake off the 5.0 to do some maint. Took all of 30 min (man, the more I work on one car, the more I hate the other car!!!

)
Oh well, Happy wrenching
BTW you may want to pull the PCM fuse (bottom left in the dash fuse panel) then put it in (about 1min) so the car can dump its parameters and start learning the new ones from the MAF porting.
