well, since nobody seems to have much to say, I will answer my own questions for future gearheads to benefit from. Be CAREFUL ordering stuff from motorsport. The bolts supplied with my cleaners were s.a.e. instead of metric. The fittings supplied were of no use. I blocked the holes on the backs of the cleaner covers with light sheet steel (from a can of imported tomatoes, no less) and good ol' JB weld. The float bowl breathers on my roundtops are in the breeze, and so is my flow guide valve (the thing that fills the gas tank w/air to maintain pressure). Aphex had run his float bowl breathers back to the cleaners like the stock setup, but it doesn't seem neccessary. The car runs better and has more power over the entire range of RPM. My valve cover vent has a breather, but my PCV is still connected to the balance tube. I'm going to check into that soon, because I suspect that putting a fresh air breather on the PCV will give more power. Now I wonder: will anyone ever read this????
