I have a HRC Stage III.....I know this is an old topic but I am having a real hard time. I want to replace the shity bolts that come with the hrc kit. What studs do I use? and where did you get them? I have heard to use GS-T studs....but the GS-T has two different size studs which ones can I use?

8mm 4g63 exhuast studs

Go to NAPA or a hardware store and buy the studs. They are 8 mm 1.25 pitch thread for the portion that screws into the head. Bring a stock stud with you to get the right length.
