Chas, the 380 flow number is at .800 lift, the Edelbrocks we do will flow about 355-360 @ .600 lift. The 2x4 set up you have is plenty of carburation for your application. The 2x4 carburator set up are always harder to tune and it depends on how the carburators were prepped. We like to use a single four for best performance and drivability. we will normaly use a 850-950 with these heads and make from 600HP to 800HP depending on the size and options.

Thanks, Keith Craft
