No and Low Compression, et al

[dbb1porter]

Need some help with an 82 380SEL (w/double row timing chain) I just inherited...PO said car was running OK when it SUDDENLY died and didn't want to mess with it anymore. His trash is my $200 treasure (or headache). Anyway, car will idle and start up on first crank, but bogs when given any gas-if I play with the accelerator I can get it up to 20 mph. I can rev it pulling on throttle and pressing down air plate. Reviewed forum (which is great!) and frequency valve checks out (buzzing), fuel pump OK, new fuel filter, OVP and fuse OK, idle control seems to be working properly-pulled off conector and idle jumped up. Replaced coil, good spark on all plugs. First thought: maybe a massive vacuum lead somewhere (car lurches when taken out of Park).

Here is where things go downhill: checked ign timing. It looks like timing is set at 20 deg? I'm guessing someone must have tried compensating with fuel mixture (increasing richness?) to keep it running???
Vacuum readings were way off! Needle vibrates excessively between 5-10" hg at idle--no where near 20". Drops to zero on acceleration and jumps up to 15" on deceleration.
Checked compression: Cyl 1 = 0, Cyl 2 = 0, Cyl 3 = 20, Cyl 4 = 130 first test, 50 second and third test...dropped in a little oil and no effect. Cyl 5 6 7 8 = all were between 140 to 150. Didn't bother to check fuel pressure yet as this needs to be addressed first.

I guess I know where start next. Does anyone have a good link with pictures that walks thru removing the head? (is the passenger side bank considered the left side-like your looking at it, or the right side-looking at it from inside?)

Any and all help is greatly appreciated!
