    Default Edelbrock heads rectangular or oval

    Starting the slow process of building my 502 MPI in the off-season. I was planning on going from to a 509 with 741 cam and CMI exhaust. I have a possible deal working on some Edelbrock heads. I want to stay around 9:1 compression. Which is the better head for my application. Rectangular or oval.
    My boat is a Conquest 28ft Top Cat deck boat.
    Thanks all!

    I would go with the rectangular heads. JMO (experience with 502 and 555 BBC, both engines blown)

    Which Edelbrock heads are you thinking of using? How do they flow? What's your overall goal?
