When it comes time to replace the head gaskets on your 6.0L, make sure you've got all of the necessary gaskets and seals for a complete job, coupled with an ARP head stud kit to ensure you never have to do the job again! Due to their sheer construction and design, ARP Studs do not have a tendency to stretch and loosen, as standard bolts do, keeping the heads firmly in place. 

This kit is available for both 18mm and 20mm dowels.
