Front suspension set up

need to upgrade my front suspension to keep the beast under control.current set up is stock suspension with disc brakes older 3 way adjustable drag shocks 4 inch wide centerlines with 165x80x15 radials that rub the fenderwell headers when turning, note this a 440 car and has 29.5x11.5x15 bias ply slicks in rear, so im thinking of going to 25.5x5x15 bias ply phoenix fx drag tires and a drag shock with a higher collapsed lenghth also a new manual steering gear and wilwood slotted disc brakes and then a professional alignment and have them check the rest of the front end parts which seem ok to me, any combo you guys are running with a big block a body apreciate your input thanks.
