New Edy heads, poor quality control what to do

I bought my Eddy,s from a member,when I had them checked they flowed 240cfm OTB.After paying for some clean up porting,guides,springs they got them flowing in the 275cfm range.Cost me but am happy with the results.:D I have close to $2000 plus the cost of Pro Magnum rockers,Manley push rods.
