The flow numbers in the article are on the 1020 bench so they will be higher when converted to the industry standard 600 numbers.
Its actually pretty funny that we kind of just built the motor in the 05 shop car in about 3 days so it could be in a magazine article.
So far the best number to date is 770RWHP. But we are working on another motor with our next stage of 3 valve heads that should when all is done being going over 300CFM.. We hope with the new stroker motor and the bigger blower to lay down over 900 at the tire.

i brought this to 2v for a comparison. i know everyone is wanting to maximize their power. for the price of stage3 2v's you can wait a little while and get
4v flow in a 3v head. these ports are turning out to be BETTER than 4v in some applications. of course ultimate will always be 4v. but for street cost 3v is taking over. it costs less per hp for 3v.

here are early(jan this year) numbers.

livernois expects to exceed the magic 300 cfm mark soon. but the real story is the port shape and lack of structures to limit laminar airflow. these heads RAM the air in.
