Don, the 69's used either the #16 or #62 heads, while the 69 RAIII, and base 400 GTO (350hp) manual trans used #48 heads. All 3 heads are virtually identical. The #48's are worth more to restorers (especially to the Judge guys) because all Judges were RAIII or RAIV. The #48 heads are much rarer, but offer no performance value over the #16 or #62.
As for cams, the auto trans 69 GTO base engine used the 067 cam, while the 4-speed cars used the slightly more aggressive 068 cam. There's also another cam known as the 744 cam, more aggressive than the 068, that was used on early 1969 Ram Air III cars, then Pontiac switched back to the 068. The 744 cam used more duration than the 068 (same lift), but was a bit too lumpy for everyday use.
The RAIV was a different animal entirely.
