Meet Stage 8 Pro Team Member Ed Gatt from Commerce Township, Michigan:
I just installed your header locking system #8913 on my 1966 GT40 engine headers (427 ci with 622 Dyno HP). I previously used the Stage 8 locking fasteners on my 1995 Dodge Viper, 55k miles and no loose header bolts. These fasteners work fantastic! I recommend these to all my gearhead friends. I have been using Stage 8 fasteners for a number of years. They are amazing!
