Yes Don, I remember that well, as I recall you had problems with them twice before switching to a '60 engine. Your's is the only post-56 tubes I've heard of that were brass. Pontiac switched from brass to stainless tubes mid year '56. The 55-56 tubes are different (round) than the 57-59 tubes. They are often very difficult or impossible to remove without destroying them.
