I'm sure the quality of the headers has a lot to do with it. Current set on the Chevelle were installed on a 396 and now on a 454. No leaks on either and I didn't have to ding them to get them in. On the motor home I installed Doug Thorley's. Very good quality headers, better than the ones I put on the Chevelle. Now I need to order a set for the new motor home, when I get the money and the time to install them.
