Update time
Engine is shaping up nicely, last time I've took the new shims and set up the valve clearances. Not all the shims are available from Maserati, and it's also min 5 order per size, so I also got some from Schrick, but those are only in 0.05mm increments. Also used a few current ones and ground down by hand.
Installing oil pump and new front seal. Using the factory tools made this a breeze
Installing new water pump. I had these on the shelf 2016, heard it's harder to get nowadays, but there is an aftermarket solution, not sure how it can be sourced:

Crank pulley was quite tricky to install. It has to be heated up on a place to 250C and then dropped onto the crank. There are only a few seconds for this, since as soon as it touches the crank, that big mass will cool it down instantly and will get stuck halfway if not properly aligned to the centering pin. Yeah I needed 2 or 3 tries.
Also replaced the timing pulleys, mine were badly corroded. Could only get the older / newer style, not transitional style I had.
Finally new bearings too
I'm currently waiting for the timing belts, first received a wrong one (for the 3V engines), then an expired one (from 2012). Otherwise the engine is more or less complete, only needs the the accessory items.
