Getting the cams timed involves setting the crankshaft set at TDC #1 on the compression stroke, and lining up the cam timing marks on the cam caps with the #1 lobes pointing outwards, away from each other. There is a vernier arrangement between the cam and the sprocket, so you can fine-tune the timing. It involves taking out the small bolt and loosening the big 22mm bolt, rotating the sprocket relative to the cam, then reassembling.
This is not for the faint of heart if you don't understand the valve/piston relationship, as turning the cams without turning the crank when a piston is at TDC will cause the valves to hit the pistons. I would recommend reading up bigtime on the Alfa procedure specifically before pursuing. There probably is a thread here on the BB on it.
