Default What makes arp head bolts better than gm?

I am wondering why everyone suggests using arp head bolts over gm bolts? Can you reuse arp bolts? I am just replacing lifters on a stock motor do i really need them or can i get away with the gm replacements

GM bolts are torque to yield bolts... They streach and are one time use. ARP gives you a torque spec and they can be reused as much as you want. There's nothing wrong with gm's bolts but if you pull the heads ever again you'll be buying another set.

ARP are a completely different type of fastener, like said, GM is Torque to Yield which is fine on a stock motor, as they are made to stretch. ARP are completely resuseable and I have used them for years on my LT1 car.

Makes sure the threat holes in block are COMPLETELY clean, blown out with NOTHING IN THEM. If there is even coolant, you will crack the block.

ARP makes, in my openion, the finest fasteners available. They use stonger alloys, more precise tollerances, and more attention to detail. The only beef I have had was a set of chrome headder bolts that I couldn't keep tight on my old Dart Iron Eagle heads. I will not use chrome for headder bolts again without a retention system. My buddy actually drilled holes through the heads of his and strung them with aircraft safety wire. The steel was so hard he had to buy specialty drill bits.

Great guys thanks for the fast response! For now I will go back with gm bolts as cash is tight.

right, right! too bad a set of ARPs are so pricey. Theyre the best bang for your buck though if youre a guy who likes to make constant changes to your setup or have a nonstock motor. Bottom line they stronger and more durable

When it comes to a $30,000 motor, a few hundred bucks in fasteners are not considered an expensise. It's called an insurance policy.
