If you have driven that car for a while with the CH4B why not see if the new RPM performer will fit and drive better than the older CH4B work scope twocents
I have buit and used several different 440 type intakes, both single and dual plane, and I really like the Eddy Performer RPM intakes on both B and RB, stock stroke 440 and stroker cranks motor in both RB and B with stock 440 size intake ports, especially on a street car up
