Review: Great quality - I know the ARP hardware is overkill for an application like this but it gives me peace of mind knowing I put the highest quality product available in my motor, they threaded in nicely and torqued down without any problems, just be sure you clean off the protectant that’s on them with a solvent before applying thread locker
Review: Highly recommended for a engine rebuild - Anything that has the ARP logo on it has my vote, I used this when I was rebuilding my lS1, great value and easy install an fit great
