Has anybody seen any flow data for big valve heads on the net? I'm looking for numbers up to .600". I'm sure there was something comparing them to a buick 300.

While I'm looking for accurate flow data can you steer me clear of bullshitters, lol.

Heres some info provided by Dan Jones in the US who I rate as a reliable source, it includes flow figures on pages 2 & 3 for light ported and stage4? Rover 3.9 heads and Buick 300 for comparison.

Lift only up to .550 not dure you'll find anything much higher for the Rover heads.
