The next time you remove your intake manifold and cuss the Allen cap screws on the backside that are such a pain in the backside to access; I have a suggestion. You can't access them with ball-ends or wobble jointed or any other fancy hex drivers and there's no room for standard hex bolts.
I spent about ten minutes with Dr. Emel modifying the bolts and it was probably the most satisfying little mod I've done in a while. Now, they can be run up with a 3/8" open end, saving several minutes of bad words while trying do them with a shortened Allen. Of course, you can still use the Allen for the final cinch down.
