Great bolts better than the original ones
Bolted right up have no problems replaced both side exhaust manifold so my Avalanche can't be happier they were very easy to install I had no issues the only problem you'll run into is if the existing bolts snap off in the heads

4.5 stars for quality, but does NOT fit Chevy 4.3L Vortec
Was advertised as fitting a 98 Chevy 4.3L Vortec. Bolt size is way too small, didn't even grab threads in the head. Quality of the bolts is fantastic, and the coating looks like it will hold up over time. Just have to find a different use for them now.

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.

Excellent replacement for stock
Luckily I got all the old bolts out easily and used these to replace. Clean and lube your threads first then use these most awesome bolts

The heads of the bolt are hollow and have been drilled for tie wire, I purchased these as replacement exhaust manifold bolts.
