Im a bit interested. How are the DOHC vrs SOHC heads, when both are aggressively ported , if both are run with large cams and high (not low) compression? I would assume that if both heads were ported for max velocity, then the SOHC heads would actually do better with large cams as there would be considerably less work on the valvetrain, especially important given that it wouldnt be run in a low compression engine. Is that true? And how does elevated compression change the relationship of the two? Is the DOHC still considered "better" in that situation in a high flow, high pressure environment?
