Some say yes (suppliers of new parts) and some say no (some users). What is YOUR opinion?

Steel bolts into aluminum.  They would rip the threads out before stretching.

 

They are fine to reuse. 

 

Subaru does not say to replace.  Only places they say that is suppliers trying to sell you bolts.

 

Unless there is some defect like bad corrosion, or boogered threads, then just reuse them.

it's not opinion - it's fact that you do not replace Subaru head bolts.

 

suppliers are providing a "one size fits all" bag of kits with more parts.  don't use them.

 

i wouldn't generally buy the kits that supply the bolts either, most of those ebay and amazon specials i've seen come with cheap head gaskets that fail in short order.  depends on the motor of course but buyer beware.
