Well, while I was at work today, I took it upon myself to clean this bitch up. I took a die grinder with a coarse barrel from my head porting kit and cleaned up all the extra junk. I matched the plenum opening to the gasket. I got it all nice, and couldn't leave the rest of the inside of the plenum looking like crap, so I went balls deep, and cleaned up and semi-polished the whole inside of the plenum. The old addage is that you're not supposed to polish the intake side of anything, but, seeing as how we're not in the carb-ed days, I went ahead and did it anyway. If I ever go with nitrous, i'll rough it up again. I'd show pictures, but its out in my car, and I don't feel like getting up.
