First time swapping edelbrock aluminum for 915 cast iron heads.

I’m planning on doing my first head swap on my 383 in my 67 Dart. I’m going from 915 cast iron to aluminum edelbrock performers. I’ve watched a few instructional videos on YouTube but still have a few questions. I though I’d put some questions out there for help. I’ll be swapping my Harland Sharp roller rockers over to my otherwise complete Edelbrock Performer heads.
Can I just reuse my pushrods and lifters? If so should I make sure same lifters and pushrods go back in the same location?
Do I need any type of modification or spacers/shims when moving my Harland Sharps over to the Edelbrocks from cast iron head?
What lubricants/supplies will I need other than listed?
Anti-seize for ARP bolts
Gasket sealer for head to block surface.
Oil for various contact points metal to metal.
Any other brake-in lubricants?
Any other suggestions welcome. Thanks
Carl
