Very nice flow from such a "small" port volume. You may have so much torque at 5000 rpm that you won't know what to do with it! LOL

From memory, Dwayne's flow bench can't flow 350 cfm at 28"H20, so it will be corrected to 28" from the 7" or so it actually pulls. On some other heads, a "bigger" bench that can flow 350 cfm at 28" will tends to keep the flow going at the higher lifts (0.700"). But that is only a rule of thumb, not an absolute.
