They are 6.0 heads and they flow 338 @ .600 lift
but the midlift is crazy. at .400 lift they already flow 285 cfm...at .500 they are 320 cfm
Keep in mind though these head were setup with a 4.060 bore. They are now on a 3.90 bore. Thats why they are not ideal. That and a few other minor things. But they are obviously still effective.
