ET Performance flow numbers and impressions
The flow numbers that are attached are the number that we got off of our flow bench which is a SF600. we used a clayed radius, a 1 3/4 straight pipe that is 7 inches long and a 4.000 bore adapter and flowed at 28 inches of water. i spec the heads out before i flowed them. the combustion chamber came out to be 72.8 cc's the intake runner was 224.7 cc's and the exhaust runner came out to 91.5 cc's installed height on all the valves were dead on 1.800 and they were packaged extremely well. one packaged up head weighed in at 38 lbs. what a beafy head. not one single detail was left out on these heads. all 10 main bolt holes have steel inserts and the rocker bolt holes are heilcoiled. waited awhile for them but after seeing them if i had to wait two more months i would have definelty be more than willing to. just want to say thanks to the guys up at ET for bringing a great product to my door.
these flow numbers are the advertised numbers that we email to me by ETP.

My heads
I'll save you some work, Brad. Here are the pictures that were sent to me from Craig at Et Performance. These are the heads I have been waiting on for so long, but it appears that may have been worth the wait.
