That's frustrating. I'm not looking forward to doing it myself. Going to have to price out getting the spare head I have scanned, but unless it's really cheap I will have to put in the work myself.
Also frustrating, I can't find any models of the Weber DGV carbs. :sigh:
How you doin, X?
Fine,fine,fine....
For a rapid reconnaissance survey
A Plastic 12" vernier caliper with depth gage can be used as a Depth Max "Demac gage" and reference datum via two platic sheets will get you close.
A sandwhich with one slick under the head and another a long the rocker shaft bolts. PE food industry sheet is what I
Then grap your Dewalt with a long 5/32 drill, and drill holes. The hole co ords and deths form X/Y/Z co-ords, and for each point of inflection, drill a new hole,
Normally, the caliper depth gage will slot through the referenace datum, which can be the top for measurement, then recalculated from the bottom for standard CAD CAM numerical protocol.
As long as you can adjust the modular distances back to the 4.08" bore centre line, you are golden. In one of the many 1969 to 1982 on line articles, Ak Millar said that the casting wall thickness averages out as 189 thou based on the production line quality assurance. So you actual accuracy will vary.
A guy in my town does 3D imaging for medical equipment; an exceptional guy who has been briefed on the log head six by me back when I was looking at a 138 teeth Cologne V6 to Ford small six block adaptor. I don't like taking paid work from the Americas, because people like
CNCDude can do a perfectly robust nth degree solid works survey for a small fee.
Because the working accuracy isn't great, and casting variations are quite large but hanged on a very accurate 4.08" modular distance, I prefer to do cigarete packet designs. For things like bellhousings, Fords production tollerances are pretty low order.
Good fortune.
Paul Simon once said, I like to go broad, and then go fine. Don't go fine first.
A man walks down the street (broad)
He says why am I soft in the middle now (then fine)
Why am I soft in the middle
The rest of my life is so hard
I need a photo-opportunity
I want a shot at redemption

When doing ShwaSixCobra's 81 Mustang Hatch 3.3 triple carb turbo schematic, I used on line templates, and then lashed them together with known accurate modular spacings. Don't go fine first, go broad first.
Doing it to the nth degree, production line Quality assurance needs a working range of castings to verfiy needed accuracy. For the old Offy and Edelbrock tripowers, and Hillborn injection, you can bet the accruacy was pretty low, and the only thing that re-established production line accuracy would have been pilot honing the core template postions of the three holes for the groups of three 1-bbl or 2-bbl intake centers. The rest always gets finshed fettled. Yeah, theres shrinkage and all the black art prodction line casting techniques Detriot is so dang good at, but it is just a working, living prototype untill you have to make 500 or more. Australian Vincent and Repco techncian Phil Irving used to just laugh at the best tool guys Detriot had on offer, how they could tool up for 10000 heads, but he said, "really, you'd be better off handbuilding twenty". And this was a guy who put twin and quad cam heads on 215 Buick Oldsmobile Pontiac Aluminum blocks, and just killed the opposition using nothing but a set of Daimler Majestic conrods and a few dozen 10 bob casting patterns. He made 195 mph motorbikes, and Merlin cabin blower equiped V twin side cars and open wheelers that trunced the opposition. He only became a detail nut when finish fettling...and man, was he a detail nut
then.

The last E0 heads are big, strong, and Pinto or Ford 2000/2300/2800 carbs plentiful.
Just remember, the T03 60 is also the Lotus Esprit Turbo and MG Mini Metro Turbo unit, spanning from 92 hp to 245 hp from 1980 to the late 80's.
The American Lotus community has unlocked Weber and Dellorto side draft carbs with turbos, the settings aren't much different to the normally aspirated European models, and they run 4.5 psi max fuel pressure on , I think, a 9 psi boost for 230 to 245 hp before fuel injection got fitted. Same with the Ferrari 208 GTS Turbo.

There are 5-1/8" Holley, 5200 Holley Weber and templates of conventional aftermarket 32/36 carb air cleaner pad shapes to cut from alloy or pannel steel.
There is enough space for three side by side, even with three water operated automatic chokes. They are about
7.48" or 190 mm side to side (Edited after rechecking...late night)
Basically, find the hard dimensions, and map them out in Paint.
I used the 5th one down, Weber's 32/36 and 38 Style B = 5 1/8 #99010.457
from
http://www.carburetion.com/Weber/adaptors2.htm
It comes into paint at an aprox 1:44.4 scale factor, with 229 pixels = to 5.125"
I do carb rebuilds, so I had all the gaskets to establish the hard dimensions, but a screen dump into "Paint" does the rest.
