Also: took some manifold measurements from the cylinder head.   Going to try to come up with a better head/manifold match.
Inlet port @ head face, 37mm dia.,  134.5mm C/C spacing.
Steel manifold @ head face, 34mm dia.
Aluminum manifold @ head face, 32mm dia.    There are some issues @ the carb face on both manifolds as well.

Custom match ported intake an option? I wouldn't think it would be too hard to get some flanges made, and tubing cut....  

Probably.   Although the plan is to thoroughly flog the existing parts first.    Since the aluminum manifold had 1.4" of vacuum @ WOT above 7600 rpm, there appears to be room for improvement both in the carb & the intake manifold.   On the 100+ bhp/litre BMC stuff I've done before, the inlet manifolds were larger volume & cross section, AND the carb choke diameter was larger.   As was the engine displacement.    You can always go bigger.   It's tough to get smaller without lots of extra parts.

... Lash settings are determined by:
1/  Height of the clearance ramp ground into the cam blank...

Finally- a breath of fresh (knowledgeable) air in here...

It ain't always about beer!

Jack, did you pull the trigger on that Dodge in Illinois?

Midget,

Want to put together a list of things you wish to validate on the dyno 5/28.   Want to total the number of possible dyno pulls to make certain we finish up within a reasonable amount of time.   Can use the old dyno checklist and the list of pulls from the previous dyno session as a starting point.   Like J. "Hannibal" Smith, "I want to have a plan" . . . . . .

1. Re-adjust the #2 Intake valve - .022 – that was the valve we replaced after last September.

2. Change out the oil filter and top off the oil.  Can you bring your filter cutter?  I want to make sure we're not creating shards.

3. Start with the shorty header and dial in the DCOE.
 
4. After we’ve got it dialed in, I’ll want to reinstall the air filters and make sure they’re not choking off air.

5. Check the LCB header and either eliminate it or proceed with it.

6. Check the short intake manifold and either eliminate it or proceed with it.

7. I hope to log Air/Fuel data to the point where we can put together a chart that we can use to have some direction as to how to adjust jetting on the salt, if necessary.  The Midget does have an A/F ratio meter.
 
8. Time permitting, I’d like to experiment with trimming the timing on the 2 and 3 cylinders, which I think are the ones more prone to detonation.  We might be able to increase the advance on 1 and 4, and still not grenade the thing, IF advance is what the engine is asking for.

Rebuilding/modifying your 45DCOE & the 48DCO I've loaned you.

Found the problem with the 45's accelerator pump circuit, you took a silver (solder) bullet in the foot . . . . .  you need some practice with that shootin' (soldering) iron. . . .
Will post pics later for a Weber on-line build diary tutorial . . . . . .    These changes should solve the problem with the 45DCOE carb.
 

  I recall a looooong time ago talking to Chris about blocking this off to increase pump shot volume, I guess the hole was not blocked off?

Or did I add to your woes!  

Look forward to a Weber tutorial Kemo Sabe-Boy style

Graham, it's really quite simple -

I soldered up the wrong hole.

Fordboy - you have the parts - if you can find the time, can you shoot a pic of which hole I filled, and which one I was SUPPOSED to solder up?

As always, I want to document the goof-ups AND the successes. 

And sometimes, the prefix of SUCCESS is SUCKS . . .
