Simple, good, reassurance
These arp bolts are what you need, they do thread more snug and tighter feeling than factory bolts. I was afraid they was not fitting properly but they did.

A must have for a 3 bolt cam upgrade.
If you are changing your camshaft whether it’s oem or aftermarket, ALWAYS change your bolts. Oem bolts are one use ONLY. Your work will be in vain and you will have to redo your job. These ARP bolts feel well reinforced and have never failed on me. Make sure to apply thread locker for extra reinforcement.
