I have received a lot of emails for the past year or so since I did this, so here is a short how to on lifting the back of the hood.
Abstract: Prop the back of the hood up on spacers to increase cooling at idle and low speeds.
Parts: I just took out one of the hood bolts (I can't remember the diameter or the thread pitch off hand) and took it into Lowe's. I went to the fasterners isle and matched the size up with 4 2" long bolts. The next parts are the actual spacer. Now, you can use washers (that is what I did for a while) but it always looked ghetto. I just used 2" long (use whatever length you wantto get desired lift) 1/2" diameter female/female pipe connectors found in the plumbing isle. Total expense was ~$3.
Spacer/bolts installed
Method: This is pretty self explanitory. Simply put the spacer on the bolt and remount the hood. Make sure to not tighten them all the way down until you check the hood clearance. If you have an S13 w/ stock pop ups, make sure they do not hit the hood when opening/closing. Once all looks good, simply tighten the bolts and enjoy the cooling.
Effect: I have an aftermarket temp gauge sourced off the upper radiator hose, and at idle in Texas August (HOT and HUMID), idle temps dropped ~6*. There is little benefit for this if you do all your cruising at track speeds, but for low speed air flow, its a hard mod to beat. Some like the looks (me included), but I did this for the benefit, not for the aesthetics, so if you are not a fan of the style, go cry somewhere else.
Final effect:
