TTI to Doug's Headers

I had a question. I currently have these TTI TTI340A-C1
NICKEL CHROME PLATED 67-76 A-BODY-3/4' STEP HEADERS on my 68 Barracuda with LA 360 I want to get new headers that are ceramic coated. My question is will the Doug's D453 headers meet at the collectors where the TTI are currently are? I am looking at the Doug's due to price. Thanks!
