i have been told to never us locktite on head bolts. my buddy just used ARP threadsealer on his ARP headstuds and they leak coolant. His was not on a LS1, but another 350. I am trying to prevent this on my LS1. I am not sure what to use....

 

LS1 headbolts are dry, they do not go thru the waterjacket. No sealer necessary.

 

i actually found that out last night. thanks for the help.
