I've bought some very good modified injectors from www.fuelinjectorconnection.com They can rebuild and flow match your current injectors. I've always had fast shipment. The one time I had a problem he sent replacements the day I called instead of waiting to get the old ones. Very good customer service and a very good product.
I have dealt with both Fuel Injection Clinic and Wilson Manifolds. Wilson is right around the corner from me. Call them in the AM. Ask to speak with John Rollins and tell him I told you to call. http://www.wilsonmanifolds.com/
