It all looks very nice!

8mm dome pistons are more like 10:8-11:1 CR. Did you measure all the volumes to see what the actual CR will be?
Or does the VX head have larger combustion chambers?

You probably know what those cams were the same as in later models, but Fiat changed the valve clearance for cam timing measurement purposes, so on paper it seems like later cams are much weaker.
Single Plane (bigger ports) Fiat Argenta 120i intake manifold
Argenta 120ie was fuel injected, so it's likely from Argenta 110.
Yes Argenta 110 manifold...my fault!
CR should be around 10,5:1-10,6:1 because of VX head has bigger chambers: they're very close to Abarth 130TC Strada (Ritmo in Italy), almost 52cc instead of 45/46cc as in my old 124 CC1 head. So static compression should be lower than 10,8:1-11:1..
I can just think what's likely to be but I've never done precise calculations..
About cams I know that my old one are like 15/55 but 9.9 lift, while CC (1592) are 15/52 with same lift: almost equals BC1 power and speed...108bhp vs. 110bhp (with dual 40's). Incredible: isn't it? Most of people think that the magic is just in dual 40 Weber and 26/66 camshafts....
Excuse me for my elementary english, but feel free to write everything you want, I'll understand!
