Just for the complete review, I'm sure these are fine head bolts.  Just my opinion, though, the key to successful head installation is a good head gasket and, more importantly, making sure the figure 8 gaskets are seated correctly using pre-head installation compression via torquing down the sleeves to achieve the perfect (ISTR) .003 proud across all sides.  Ask me how I know!

If the head gasket is compressible, you need to retorque.  It’s not  
that the studs stretch, it’s that the head gasket compresses.

As old and decrepit as I'm feeling this morning, maybe I'll order some

When retorquing head studs of any type, one should back off the nut 
first, making sure it is loose.  Otherwise you may get erroneous readings.

And for those of you not living in the United States, AARP = American 
Association of Retired People.
