You cant go wrong with the modern aluminum heads compared to outdated , crack prone iron heads. As far as I know an out of the box Rpm head will make similar power to a ported factory iron head. Bolt em on ! Depending on the car combo, even the lower $ Eddy Rpm's or 440 source heads can go REAL quick at the track.

I don't recall them listing an advertised flow #. All I recall is the advertised CC of the runners.

Just to reinforce what others are saying. My small block Eddies flowed 217 stock on the intake with a 4.03 bore plate. Not 255cfm that Eddy says. I called the tech line and their response is that their numbers are accurate to 10% and that they use a 4.125 bore. That means they take the real number and inflate it 10%. I was really disappointed with the outcome. My J heads flow 255 and to put the eddys on would probably go slower.

Bill I think in the beginning, they were hyping flow numbers in the magazine ads of 290-something. I've had three sets on two different benches that were no where close to that...

http://www.edelbrock.com/automotive_new/mc/cylheads/chrysler/bb_perf_rpm.shtml
Doesn't give much info as to how they got those numbers though
They simply left out the part about the shop fan blowing another 30 cfm in there!! Or...to be fair to Edelbrock, maybe they used the bench at Westech...
