Valve train on 69 383 with Eddy heads

I have Edelbrock Performer RPM aluminium cylinder heads and a Performer RPM cam shaft on the original 383 in my 69 Charger.
All this is installed by previous owner, but I'm changing the cam because it is wiped out. During assembly I found that at least one of the pushrods are bent (yes I should have checked them when I took them out).
In earlier conversations with my parts supplier I was told the stock non adjustable rocker arm assembly and stock pushrods could be used with the heads and cam in question. Which the previous owner of the car has done.
Now I will order heat-treated chromoly.
Can I use the stock rocker arm assembly or do I have to get an adjustable one?
If the stock actually can be used, does anyone know if the pusrods should have stock length?
Guess I can find some answers online and that I might have to measure for push rod length....

Thanks!

you should be able to run stock rockers. the big issue i had with edelbrocks is push rod length and rocker geometry.

Guess I'll just get me some adjustable rocker arms.
Any suggestions on what to buy?
I'm not sure I would sleep well at night getting the Speedmaster rockers my parts supplier has in stock.

How big is your cam, how much lift? In my opinion, any non stock cam needs adjustable rockers. You really need to take a close look at how the rockers sweep on the valve tips with the EDE heads. Also make sure you have good clearance under the rocker (doesn't bind on the valve spring) at low lift.

Yes, I guess you're right. Won't be using the stock rockers. Got a new set of Comp on it's way.

I have a feeling I'm asking questions I should know the answer to in regards to what I'm dealing with here, but at least I know I need help, haha. I'm about to install Comp Ultra Pro Magnum roller rockers, at this point to determine push rod lenght, but I'm not sure about the adjusters.
Am I supposed to have the adjusters, which are socket style fully turned out, or should they be somewhere in between?
The instructions that came with the kit isn't much help and all I can find on the google is for Chevys...

Also, should I add preload to the pushrod length when using adjustable rockers?
If so, how do I know what lifter preload to add?
Is this in the same range for most hydraulic lifters, is it a set value by the manufacturer or does it have to me measured?
