    These bolts are of better qualtiy and look better than oem
  

*by A***. on Reviewed in the United States on November 13, 2023*

These bolts are of better qualtiy and look better than oem Just did the DOD delete on my truck and if you are removing the manifolds DO NOT put the oem bolts back in they are prone to breaking on removal but I wouldn't trust them to be reinstalled either. If you're pulling the heads you can get the old bolts extracted that don't come out but don't put oem back in, these are equivalent to arp in my opinion.
