I'd say where's Waldo but that's pretty obvious..

The echo of open headers there would be awesome.

Don't want to be pushy, but did you get a test drive? All good? Done deal?

No test drive, carb doesn't feel right. The whole thing just seems lazy. It doesn't bog, but it sure isn't crisp. I feel like I had the transition slots squared and it was idling at 1200 and had to close them a lot to get a street car idle around 800, I'd prefer 750rpm honestly.
 
Congrats!
 
ok girls, here's todays rundown after it got running.

vacuum advance plugged
Cold start numbers:
6.5psi fuel pressure
18* base timing
idle speed 1070rpm
AF ratio pegged at 18 on the gauge. gauge normally sweeps when warming up, so I don't believe this was a malfunction, but maybe?? with the duration of this cam perhaps all that extra air getting into the exhaust makes it seem lean when engine is cold.
6" vacuum, which was likely getting the power valve involved, which may be why it initially wouldn't stay running, but doesn't explain the lean condition once it was running a bit
oil pressure 60psi

at 175 degrees water temp (it doesn't ever get up warmer than that with my water pump and fans running):
Oil pressure 42psi, jumps to 55+ when throttle comes up
adjusted timing to 20*
adjusted mixture screws out from 1 turn to 1-1/8 turns
vacuum 11-12".
AF ratio 13.7-13.9
brought idle speed down to 800rpm, oil pressure came down to 36psi

gave it some throttle to see overall timing since base was 20* and discovered the Chinese bushing I have in there is acting more like an 8* bushing or my springs are being weird. max timing was 28*, though I cant verify exactly what rpm that was at, as I don't have that many eyeballs. somewhere between 2800 and 3200 it was all in.

after shutting it down, a few minutes later I decided to check header temps at the primaries, kind of a way to see if I had some lean cylinders even though this isn't the greatest test because the IR thermometer is in the shaky hands of yours truly.

Cyl 1 140*
Cyl 2 136*
Cyl 3 160*
Cyl 4 160*
Cyl 5 152*
Cyl 6 150*
Cyl 7 150*
Cyl 8 151*

Have fun with this info. Let me know what in the hot fuck to check or do next. TLDR

Next? I say drive the fucker, bring a screw driver and play with the carb along the way.

I'm concerned about all in timing and would like to hook up vacuum advance because the exhaust currently burns my fuckin eyes!
