You can try to clean the head bolts using either a wire brush and solvent, a bead blaster or soda blaster. After the bolts are cleaned thread them into the block to make sure they turn freely. If there is any indication that the threads are damaged do not use the head bolts.

Do not use a sandblaster to clean the head bolts since that will cause erosion of the threads, making the head bolt unusable.
