01 heads don't flow as well as the 03/04 heads, they aren't that much behind, but its just a little difference

the cobra heads and c heads are essentially identical in flow rate, the cobra heads are little more setup for FI, I believe the springs are a little different as well, basically imo you can think of the c heads and 03 04 heads sinomously, but the B heads stock arn't great, but with a race port and high performance valve train all 3 series of heads perform essentially the same

That's crazy to think about....
If the 03/04 heads are better, that means the stock supercharger makesLESS THAN65 more flywheel hp than the 99/01 cobra's. Correct?
I have been told they underrated the 03-04 termies to where they are at around 425 or so flywheel but still....
Is there anyone that has info on this? flow charts or anything... Im curious to see if they are the same heads, and if not, how much more one flows over the other (if that makes sense)
