Hi and first off a warm welcome to BB
Lets see a photo of your alfa (kind of an unwritten rule here)

the intake cam you have has the mechanical VVT, came with the first L-jetronic cars. Some actually prefer it to the electronic VVT, but's that six of one and half dozen of t'other!

Later it was changed to electronic, solenoid operated VVT, with the solenoid on the front of the cam cover.

some info on the mechanicle VVT for you here:
