I was glad I bought this kit. I ended up needing to remove my heads after installing them and glad I used these ARP head studs instead of OEM bolts which are torque-to-yield, one-time use bolts. The ARP studs were only a few dollars more than OEM bolts but paid for themselves when I had to remove the heads due to a problem. If you're questioning whether you should buy studs or not for an upgrade, like I did, take my recommendation and buy these.
From first looks they seem one of the better qualities I've looked at we will see how they hold great shipping every time
These are great quality head studs. They will serve you well. Compared to alternatives, these are the best bang for the buck.
What can I say, they're great studs! Holding strong with an oem head gasket running 22psi of boost on a 20gxt Blouch turbo.

Q: Probably dumb Mike8015 years ago
Probably dumb but I’m currently in the middle of getting everything together for a frankenmotor ej25 and was hoping that you could tell me if these would work for said build? (Yes I read the other questions about the regular model fit but this is a bit irregular) pic of my ugly multi color gc because it gave me the option.

A: Without knowing the specifics of your build we cannot confirm fitment. We would recommend reaching out to one of our Customer Service Representatives in regards to your fitment question.
