360 Magnum building on an existing bottom end

I went with the Edelbrock 2.02 RPM Magnum heads. Just installed them OOTB. I used Comp Cam 1.6 rockers.

Some day I'll run it on a chassis dyno.

Do they perform well OOTB ? What kind of HP do you estimate your engine is producing ? Do you think these heads can support 500+ HP ? Did you buy them bear and build them to your cams needs or buy them all assemble ? What cam are you using? Thanks in advance for the info.
