Edlebrock RPM head clean up

I am going to take the advice and go 9315s. Keep the retainers and order the 611 locks. The Edelbrock are a dual spring retainer but 7 degree. The springs will be returned. They were previously opened anyway.
Shipping is a bit slow now due to Christmas.
My machine work was done 15 + years ago and the cam and heads were bought over two years ago. To say this project is slow would be an understatement. The car will be fully restored.
Hoping to have the engine finished and in the car this winter.
Some things I still need to buy.
Cam button
Distributor gear
Head bolts or studs

The roller cam process opens an expensive can of worms. LOL
I bought the AR engineering timing cover and debating on nylon or bearing cam button. I would turn the nylon cam button down to desired depth on a lathe.
I was leaning towards the melonized gear from Hughes. But I recognize the potential value in a sacrificial gear also. Ahhh

Thank you PRH, and all who provide input. I very much appreciate it.
