I picked up a 1983 Bianchi Sport SS for $200. All original components. Manufactured in Japan. Good deal?

Anyway, I have been going through and servicing all the bearings. The headset seems like it's notched in the forward position. That is, it feels like it wants to stay in the forward position and once it's moved its fine. Is this normal? Was this a built in design feature?

Pics for attention
