I was and still am a bit skeptical but they have been holding up fine to 15 PSI of boost with 9.5-1 CR. I will most likely order a set of Xotic or ARP to have on hand when these go bad but they seem to just fine. Update: it has been about a year and half running these studs, had the motor apart a few times and reused them each time. They're holding up really well. I've ran 18psi of boost on my 408 LS with 9.8-1 compression.... no issues whatsoever. Highly recommend these if you need a inexpensive option delivered fast Review: Holding up. Worked perfectly - Used these on a budget rebuild on my lm7 5.3 With new 862 heads. I torqued them to arp specs last round of torque was 75ft lbs Make sure to lube the washer and nut so it torques correctly. Otherwise the nut and washer will kinda bind up during torque sequence. No issues with this kit at all. They look nice and they gave 1 extra of each length. DO NOT TORQUE TO 100FTLB GO 75FTLB AND YOUR GOOD. ## Features - Application: The 12 point head studs with bolts kit is compatible with 98-02 Camaro/Firebird F-Body. For 97-03 C5 Corvette.
