Hello and Help ME!

[frankencar]

Fellow enthusiasts!

I need some help. Firstly, I'm new to the forums so hello all. . I have looked at a lot of threads regarding adjusting valves, but the instructions on each don't seem to work for me. Firstly, I bought the car from a nice gentleman who had done a variety of poor repairs including cutting holes "strategically" in the vacuum line (I assume to get it to run better somehow), bondoing in the rear trunk latch, Cutting the front floor pan to access the broken front hood latch etc. I'm a self-taught mechanic and have an old shop manual and some of my dads old tools (he used to drag race semi-profesionally and had a few porsches) I've done a variety of things that have made the car semi drivable, but idle fluxuates slightly, and I haven't taken it on the highway yet to really clean out the carbon deposits like I'd like to. I am in the awkward position of having a nice lift at my dads house (see photos) but am a college student and have very little expendable money to buy parts or other accouterments. That's enough about me, the issue is more important. Please help me fix it so I can drive this thing!

I started by setting the pulley to Z1, which assuming this engine is a 1978 3 liter SC given my research on the engine casting numbers (see photos), is the left most of the two small marks, the right one being 5 degree BTDC. Hopefully that's correct. I set the intake and exhaust properly on cylinder #1 with the Porsche type feeler gauge. I rotated the crank pulley clockwise (viewed from standing at the back turning the fan) and to what I believe to be the 120 degree mark at about the 4 o'clock position if Z1 was 12. Problem is, I have no adjustment on cylinder #6. I tried going around again, still no adjustment (play on tappets, intake or exhaust) on cylinder #6. The rotor doesn't point to #6 at 120 degrees and I know that for every 360 degrees of the dist, the engine turns 720 b/c its a 4 stroke so I doubled it, just to see, and the #6 tappet was still on the side of the cam, not BDC. It also doesn't make sense because the rotor is pointing past the #6 cylinder, and it seems to me that to adjust the #6 cylinder the rotor should be pointed at it...(I could be wrong)...I've read a bunch of different stuff, tried a bunch of different stuff, but I lack the knowledge necessary to complete this task and am about at my wits end. I tried following this video (https://www.youtube.com/watch?v=dS7jtsx-t_4) I tried various pelican threads (Pelican Technical Article: 911 Valve Adjustment Made Easy)
I'm attaching a variety of photos...I'm sure I'm missing something. Please help if you can.
