Switching to a solid roler can be expensive. It put allot of added stress on the valvetrain so you will need to get good strong parts. This is what I would do to be safe.
One peice pushrods
titanium locks and retainers
new springs
and a stud girdle to keep it all on track.
If you order your heads complete you can tell them you are runing a solid cam and they can make the changes.
