1963 383 heads with pedestal rocker shaft mounts

I have a set of newly rebuild 2463200 heads from a 63 383. I don't have the rockers or rocker shafts from those heads or the pedestal mounts for the shafts. I understand that maybe 1959 to 63 big blocks all had the pedestal mounts? So I'm trying figure out what I'm looking for. Will the rocker shafts from a later big block head mount onto the pedestals or are they different also? I have some later heads that have the rockers and shafts. Do I just need to locate some of the pedestals? These are the original heads to the car so I would like to use them. Thanks for any help.

There are two versions of the pedestals, one for the stock stamp steel rocker arms for use with hydraulic lifters and one for the ductile iron adjustable rocker arms used on the motors with solid lifters, Chrysler 300 letter series cars, M.W. cars and maybe some marine and industrial motors, not sure about those motors though PM me if you need them for either type, I may be able to help you get some
