Known for being the best in aftermarket bolt and stud kits, these ARP studs are good for all years and models of the Stealth and 3000GT - both turbo and non-turbo! So when you are building up your motor, these offer an upgrade alternative to the factory head bolts. Sold as a complete set of 16 studs+washers+nuts good for BOTH heads. Note: Mitsubishi lists the same part number for all 3000GT head bolts, including the SOHC, so these will work across the board on the 3S platform!
Note: ARP includes instructions with their kits, but here is the 6G72-specific ARP Head Stud Instruction Sheet in PDF format.
