I couldn't get the adjustment of the headset just right on the Raleigh I have just done up. To take out the play meant the bearings were too tight. Initially I put it down to simply having to let all the new bits bed in, but decided this was wrong thinking. To find the problem I have just stripped out the whole headset assembly which only took a few minutes. The fault quickly became obvious. I had installed the lower bearing cage upside down. Must have been a senior moment. Anyway, with correct orientation and all reassembled the assembly is perfect. Also, though not actually an error, I had routed the brake cables to the front of the handlebars. While the bars were off the bike, and the front brake was removed from the fork, I re-routed them behind the bars where they look better. Last night I also swapped out the semi sealed bottom bracket for a fully sealed Shimano unit. I think I can now declare the job's finished and is a good'un.
