    Default 504 square vs round port cylinder head?

    Hey, im just building a 1974 504 for hill climbs and rallys at my local club.
    Im just in the process of sorting the motor, clutch and brakes etc.

    What cylinder head is better for tuning, the square or round port?
    My xn1 has a square port head. goes really well.
    Was looking at a round port head thinking i could do new intake and quad carb setup?
    or should i keep the square port and just get a new carb , cam, push rods and build some extractors?

    Thanks,
    Pablo

    505 SLI cylinder head and Argentinian inlet manifold with a Weber DCD is a match made in heaven for performance, or use a falcon throttle body and megasquirt.

    Weber carb to Falcon TBI conversion
