The edelbrock rpm heads have std port sizes, so you will need an A&A std port cross ram. Steve Magneta did a good article on a buildup of a similar motor in Mopar Muscle. The rpm heads can be ported to max wedge size, but they get thin and most shops recommend welding. The victor heads and Indy 440-1 are max wedge size, but will require a more expensive offset rocker. If the majority will be on the street, stick with the stock port.
