I use a .039 restrictor in each oil line on my motors with two oil lines with Harland Sharp true roller rocker arms with solid roller valve springs to help cool the springs If your rockers are not true roller bearings on the shafts then I would try it like you have it now and change it later, if needed
EDITED: Are your T&D single shaft or paired shaft rockers?
If yours are the paired shaft system you need pushrod oiling for them
If not, continue on
