The 67 engine DID use a 2 bolt main 327 4" bore block and a steel small journal 283 crank, so the assembly was very light for an OEM configuration. Also, do your early 462 heads have 2.02 intakes and 1.600 exhausts? I have a pair of those on my core shelf, and the rocker studs are cross drilled through the stud bosses with little roll pins through them and the studs. Only motor I ever saw like that were 62-65 hi po 409's. I wonder now if that is what these heads I have originally came on, if not a 68 325 horse 327. Very interesting engine build you have here.

The 302 had a special 3" stroke crank, not a 283 piece. You can check the date code on your 462 heads, some had 1.94 intakes. The small roll pins were an early common fix to prevent the press in rocker studs from pulling out.
