Not speaking for Bernie, but I believe he was inferring that if the runner texture does not match the other "cast" textures on the same head there "may" be a problem. For instance, in a 441 SBC head if the textures of the runners is not the same as the texture on of the cast surface under the valve cover, or the exterior of the runner on the underside of the head, then there "may" be a problem. Therefore if you were to do some runner "work" you would have to re-work all the cast surfaces on the head (time and $$$).
