These bolts are of better qualtiy and look better than oem
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.

These fit the GM 5.3 perfectly
Not a whole lot to say. They are exhaust bolts, and they fit my 2005 Suburban with it's 5.3 liter engine. I put some copper anti seize on them and torqued them down. They seem to be holding just fine a couple of months later.

Not as pictured in sellers photos
The heads of the bolt are hollow and have been drilled for tie wire, I purchased these as replacement exhaust manifold bolts.
