i am looking to install some arp head studs on my 06 i have 123000 on the odometer is that to high mileage to replace each one at a time i dont dog the truck and i have run royal purple in it since i bought it if that matters cant find a definite answer in my searches any help is appreciated

 

No worries one at a time is fine!

 

ok cool guess ill get started then, what mileage is it a bad idea to do them one at a time

 

There is none as long as the head gasket is good! Can't do it after lifting the head! "Extreme boost".
