Don't even mess with the 40's Dave. Put on the 45's. You have way more head flow capability than the 40's can keep up with I believe. I don't thing you can get big enough venturis for the 40's to let them flow enough air. You will not be happy with them. The 45's on the other hand..........hold on!! They will make you smile.
