Horsepower limit for out of the box Edelbrock RPM heads

Why did they make a Victor head? Because thank God some guys do want to go fast. I wish I could have gone with a small block in my heads up car but I already had to much tied up in my big block stuff. It’s a be-itch to work on and I don’t know if I will ever finish that car by myself. W8-W9 combos take to many tricks to get there and to high of maintenance at the rpm they run at. I would love to have a Ritter block, Victor headed, nitrous combo as it would be so much easier to work on than a big block squeezed in a stock front frame stock firewall set up.
