I don't know the flow numbers on these old Desoto heads but they did look a little backward. I ported the intakes until they needed tubed and then used smaller valves on the exhaust. Since the motor will be turboed I'm not too worried about intake flow. Just a little street rod that will never see the drag strip. Mostly local car shows. Lets not tell Gene Adams about the poor performance of the Desoto heads. He was only able to go just over 200 MPH in the quarter on 305 cubes unblown. But then it is all about exhaust flow when running nitro. You don't need alot of intake port when dumping in liquid nitro. You do need alot of exhaust flow to get the burned mixture out, hence-that's why the Chryslers dominate the fuel classes. Bill
