yes they can, the 33 cfm comes from having the head/manifold,carb flowed ,the difference between the 44 and the 48's on the flow bench is 33cfm at 560lift

intake port flows 288cfm @.560lift

head/manifold flows 280cfm@.560lift

head/manifold/48's flow 256cfm@.560lift

44's 33cfm less @.560lift

the heads are ported alloy windsor snr's

if i was to run a four barrel,would i see flow of 280plus @.560lift?
