Campagnolo 1.18 hidden headset on a 70's steel colnago frame?

[jedblack]

i just bought this, but now am unsure if i can use it?

i have a 70's Colnago Classic steel frame, steel fork(but wanna use a carbon fork)

i'm thinking i may need a 1" treaded headset? if so is there a conversion kit? i think Chris king may have something like that

BTW, i just bought the Park PK-57 so i can start building/rebuilding my own bike instead of paying some guy $150(nyc price) for every rebuild. So this is my first bike buildout... sorry for the "green thumb" Q-n-A



thanks for all the help my fellow cycling fanatics !!
