audi 90 20vt big turbo 034 IIc stand alone first start

This is the very first attempt at starting my 1990 audi 90 20v since it was all stock.
The engine is a 2.3 liter 7a block crank and head I rebuilt it with new bearings, bolts and rings using NG pistons and ARP head studs. I made the tube header out of schedule 10 stainless, added a holset hy35 turbo from a dodge cummins diesel, the engine is run by 034 efi full stand alone coil on plug management. I built the harness from only the supplied flying lead harness supplied with the ecu. The car still has a long way to go but at least it runs again!

how does the inlet cam operate 3 valves?

2 of them yes, but how does the 3rd valve get opened as it is not aligned with other valves?

do 2 have buckets and shims and one have a rocker type thing?

it is a 5 cylinder with 4 valves per cyl. But many vw/audi motors have 3 intake valves and 2 exhaust. They just use an intake cam with 3 lobes per cylinder. Just look up a picture of a vw or audi 1.8t head.
