Steve, while the 301 block is physically different it still shares much with its bigger Pontiacc brothers. The reason your '78 manual groups the motors as it does has to do with GM using "corporate" motors in their cars of this era. The engines are grouped acorrding to the GM division that produced them.
1 is Buick
2 is Chevy
3 is Pontiac
4 is Olds
Deck height is the distance from the crank centerline to the surface where the heads mount, the deck. On the 301 this distance is shorter than the standard height on the 326-455.
