Aren't head bolts torque to yield?
I thought that they were.
APR studs are about $110, but you can get stock bolts from the dealer much, much cheaper, and probably still cheaper if you buy them from
www.toyotaworld.com ...unless the shipping exceeds the savings.
I think that my local dealer charges like $3 a bolt.
Here is a link to torque to yield info as well as other head bolt info as well, that may be of interest:

I know that my head bolts were obviously unusable because the threads had noticable wear.
