are you sure that they're not offset bellhousing dowels?  Those have a use.  Can't see a use for offset head dowels.

Offset cylinder head dowels are used to properly locate the combustion chamber over the cylinder. Factory tolerances can be way off the mark sometimes so do not take anything for granted.

if the are for the "b" motor heads they are to move the heads to place the valves more in the center on the bore. this way you can get a bigger valve in the heads and have less strouding at the edges of the chamber, like the sm blk moper has. if the are for the bellhousing they are to center it to the crank. this is especially helpful in a clutch car.
