Head bearings and their positioning

[customhead]

I am putting new 6004 c3 and 6003 c3 bearings in a sport head that I am repairing.
The thing is now that it is bare I cannot tell looking at either the parts file, the ducati workshop manual, or the haynes manual how far in to push the smaller 6003.
the 6004 slides into its position but I am wondering how to place the 6003 correctly.

any help would be appreciated
