Default Vacuum gauge installed

I just put an Autometer vacuum gauge on my 98 Legacy GT. I highly recommend this gauge for monitoring the functioning of the valves,rings,headgaskets, and vacuum hoses. I hear of headgasket failure in the phase 1 2.5L and I think I am starting to see the first symptoms at 65000 miles(bubbles in coolant, dark colored coolant). The vacuum gauge I think is more important than the popular oil pressure gauge because the 2.5s don't have as many problems with the bottom end for MANY miles(+-200,000 miles?). Also, a water temp gauge would be the best diagnostic for overheating due to headgasket failure,yet don't we have a factory temp. gauge already. I hear of people having the headgasket blow with no symptoms(factory gauge overheating), but I think you would have to be oblivious to not notice a head gasket going! I think the vacuum gauge is a way to notice the subtle changes in the engine. I am just suprised noone ever talks of installing a vacuum gauge in their NA Legacy.

can you post up some pics of what it looks like in your car? I want to install gauges in my NA legacy SUS and was wondering what I should do. I know I wanted the oil temp and something else just wasn't sure, but thanks for the info.
