Rather that worry about the intake mani, you can find some plate steel and some pipe that is about the size of the long alt bolt. Cut both to fit, drill three holes, weld the pipe to the plate and you are set. Just test fit 100 times to make sure everything clears. You can find much more clearance this way and you won't have to hammer the frame rails.
There is a Subaru alt that is smaller that could give you some more space too.
Forgot to add you will need a spacer for the crank pulley to do this for certain motors
