Then your really faced with two ways to go about it.
1. Modify the intake to match the W2 heads, or
2. Shelf the W2's in favor of a standard head like an Edelbrock, Pro Comp or other like head.
While it will not flow as much as a ported W2 would, I think @ 280+ CFM, the power it is capable of should be good for the street. They are capable of 550HP.
Sell/swap the W2's for ...... To run a 6 pack?
