I am looking for the flow numbers for the following aluminum heads FMS-6049-X307 . Not looking for a comparison chart , but that would work as long as it showed the air flow data for the head specified in this post. Thanks in advance.

There is a bunch more out there if you search.
My advice, as someone that was once very much into flow numbers, don't put too much faith in them, too many variables. When you find other charts, you will realize that the numbers are completely inconsistant. You don't necessarily get more power from a combo just because of better flow.
I've also seen gt40x heads perform really well, have them valve jobbed, spring seat pressure done, and bowls cleaned up, worth every cent.

The heads are on the car, not looking to purchase other heads. Was just wanting to input the data into Desktop Dyno 2003 to get a rough number before the Diablo Chip addition & dyno pulls. Result will be more presice with correct flow numbers rather than selecting a generic head that is offered in the program. Was just wanting to test out the program to see if its worth the effort. Alot of searching for the data, when a trip to the dyno will answer the question much faster 
I agree the gains will be minimal depending on your exact combo. Whats done to the car?
