M'mmmmm, Valver 'rocco.
ABF all the way, innit.
IIRC the K-jet variety valver that was fitted to the OEM 'rocco had the throttlebody port the opposite side to all of the other 16V inlets, which is why it's much feted by those wanting to turbo-charge the 16V lump.
As it's the Golf1 floorpan it has different engine mounting to the G2 and G3, so you might need to have a root about to see whether these work OK with the tall-block ABF.
