I just did my knock sensors and my bolts came up great after a bath of degreaser. That being said, here's the diagram for the intake. From what I can remember, it looks like you'll need 4x 90148-80002, 4x 90119-08609, 4x 94623-10800, and 4x 90179-08117. Might be better off just taking the bolts that come out down to the local hardware shop.
As for some insight:
this thread is a great reference for torque specs. Also, it might be overkill, but I used
paint pens to mark holes and bolts, which I then put into a zip lock bag. It made re-assembly dead simple.
