Gas flowing out of exhaust

I have a 2003 Lancer OZ Rally that is either not burning fuel correctly or is seeping too much fuel and I have no idea why. So much gas is going into the engine that it's leaking through the exhaust manifold in front of the engine. The problem originated with the car not having any acceleration and stalling on occasion. I found out that both catalytic converters had been clogged so I replaced both of them for direct fit Magnaflow Cats and that helped get some acceleration back and it started stalling less frequently. Compression is at 130 PSI on all 4 cylinders. I also have no check engine light on but I know that the car is misfiring because the engine is running rich and the cat is glowing red (presumably because of the unburnt fuel) and it begins to leak through the engine head and exhaust manifold gasket.

I've already replaced the following and the issue still hasn't been corrected:
