The -REW side housings have different port placement than '74-85 side housings which were more or less the same 12A/13B.
The port timing might get you there okay since all of the major dimensions are the same all the way back to 1967 (the Chevy V8 has been redesigned three or four times since then...) but you'll have to watch for changes in the runners and adapt as necessary. |

(it already has a slight street port) |
