Default Missing head dowel pin - options?

Should I replace it?
Will I be OK w/out it?
I need to put this motor together today and no one in town has a pin for an LT1/SBC.

Yes you need it. Don't even think about not using it.

The small 1/4 dowels on the head surface of the block. They are mostly there to align the head gasket and help keep the head in position while assembling the engine.

Millions of SBCs have been manufactured since 1955, and all of them use the same dowel pins.
