at what point are headstuds required other than 50 psi boost? certain egt or hp range need studs?

 

for the cost and the time it takes tinstall they shoul dbe done with any turbo upgrade or injector upgrade. Since the top of the motor is apart to remove the injectors

 

studs are needed once you are adding more boost/fuel which increases the combustion pressure which causes the head to lift. the studs provide the extra clamping force to keep the head from lifting.

 

Depends who you ask some say the 3rd gens are good to 55-60lbs stock. For all the guys modded on the various forums I sure haven't seen too many posts about head gasket troubles.

 

how do i know when its time to add them, is there a certain hp range or just given boost/egt levels?

what exactly is involved w/ the install? can they be installed w/ the motor in the truck and the cab in place, is there enough room to work? also what is involved w/ installing injectors as well? does the head need to come off to install injectors?

 

i have stock studs, bigger turbo, nitrous (100 shot) and im pushing 49 psi. not problems yet, knock on wood!

 

i have talked to a few shops like enterprise sheids and a few others and all of them have said that the stock head gasket is good to 100psi of boost and they all said they would not do fire rings on my head, that they have been having way to many problems with the fire rings on street driven trucks. they recomened head studs after 70psi

 

ghost let me know about injectors i can swap them out in about a hourand the only thing that needs to come off for injectors or head studs is the valve cover.

 

so how do you pry the injector out with the fuel lines and connecter tubes still attached? and get the studs in and out with the rockers still on??I did both at the same time.you all ready have the top of the head apart so kill two birds with one stone.
