CNC eddy heads

I see they are available from Bulltear, anyone have the actual flow numbers/valve sizes because I only see they flow 300 at .500 lift which is good but I would like to see the whole range if possible(low lift flow is as important as peak flow. Concidering getting some but debating between the Indy SRs or the Edelbrocks and put bigger valves and port them.

Thanks!! What about CSA and chamber CC? Also are the rocker studs 3/8 or 7/16

CSA is for velocity basically when flowed at 28lbs those flow numbers are what you get. The ports are a result of hand porting by Thunder heads of MN. They are known for their Hemi heads and big block heads although they do a very good job of small bock chevy heads. 54-55cc chambers and the stud size in OEM edelbrock which I believe is 7/16
