So big question here. How much porting would be involved going from round to oval and would I be able to get similar to the same flow rates from doing this as I would get from an oval manifold?

I ask because I found a round port manifold and there is enough material to port it to oval, but what would be the point if the manifold still restricts the flow somewhere between the head and carb in the runners? Sadly I can't see this part in person so without having it in my hand I don't know how open the runners are.

I'm very tempted to throw this carb money into getting a wilwood pedal box and master cylinders and just going for dual DCOEs next summer. Those manifolds are much easier to find, but then I lose the brake booster and have the job or routing new brake lines.
