Alright, I isolated all vacuum by capping all vacuum on the engine, set timing to 5 degrees, replaced all rubber hoses (only one is a brake booster line, go figure) and ran a compression test.
Compression is averaging at 135 across all cylinders (varied about 4-5 PSI at the most), and the plugs were a nice golden brown.
Still idles rough around 800 (if at all) and struggles to idle smooth around 900-1000. I also noticed a slight misfire at idle occasionally too, so I need to dig a little more into this.
