Seriously, for the price, ARP is simply the best and when you need to rely on the steel to keep that high performance engine together, ARP is the answer. I could feel the quality when I opened the package and am very pleased at how these bolts installed. If the engine fails, it won't be ARP's fault! I have head studs and manifold studs which are ARP.

Bought these to use when overhauling my tired TBI in a 1991 C1500. The TBI manifold must be thicker than on a carb small block, because these caught threads, but were 1/4" shorter than the OEM bolt. For that reason, I wouldn't recommend them if you're doing what I did. Ended up reusing the originals, which probably wasn't a great idea but I'm not worried about it.If you know these are the correct length for your application then I'd recommend them. They're the great ARP quality everyone has come to expect.

Very disappointed in this purchase. Opened the package and the bolts were 8mm instead of 3/8"x16. Had to buy bolts drom autoparts store to install intake. VERY DISAPPOINTED

Shipping was fast. I took a shot to see if these might just be what I need for my new headers and worked perfect. A++

No reason not to use these bolts if you are doing anything other than bone stock. Best value for the money.
