Horsepower limit for out of the box Edelbrock RPM heads

Hello. I am curious what type of power people are pulling out of box stock Edelbrock RPM heads. I am planning a 408 build. Looking at forged Eagle rotating assembly, 10.5:1 compression, hydraulic roller camshaft in the [email protected]; .550 lift range.
Are the Eddy's a good match in this range, or will they be a bottle neck?
Thank you for your help.
