258 head bolts

Why are 4 of the head bolts on my 78 different? Those 4 have a threaded portion extending up from the head.

I think those bolts were also used to fasten the OEM valve cover on that side of the head.

They mount the brackets for accessories.

Mine holds the power steering bracket. The bracket also holds an additional pullet for the serpentine belt.

They are very common on the I6 engine for both the 7/16 and 1/2" head bolts. Only on the drivers side of the head.
