In all cases, A-engines have the oil flow though the right center head bolt hole, hence the smaller-diameter bolt.

- The engines through model year 1973 have the oil passage drilled in the head. These engines are easily identified because they have the distributor under the #1 spark plug.
- The 1974 and newer heads have the oil passage drilled in the block.

So if you put newer head on old block, you need to drill a passage.
Open in new window

Boss on outside of head for oil passage
Some of the newer heads have the boss, undrilled, while even newer heads have no boss.
