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!
