Does the block have engine mounts that bolt to the front of the block or on the side? The '55-57 blocks had front mounts only. My reference shows that block casting number was used '56-67 on 283s.
It looks like the heads could be from a 307, 327, or a 350. From that I would guess they would be fairly large chamber.
The intake was '69 as you stated and used on 307 and 327s.
If I had to make a guess, I'd say you have a 283. Large chamber heads on a 265 would have very low compression.
