I've read through several of the various posts regarding 4V vs 2V vs Aussie heads. OC vs CC. After market vs factory. Port plates vs port inserts vs port flange plates vs none. Lot's of good info, and lot's of opinions.

Has there ever been a side by side dyno comparison of these heads (and any of the others available for the 351C) and plates using a single base engine and comparable intake/carb?

The more I read the less clear I am on which way to go. Several books try to cover the topic as well, but still just more opinions.

Any direction would be great,

Thanks,

Keith
