When to add head studs
I was wondering what PSI of boost will my stock head gasket take? Also when i added head studs can i put them in one at a time on a high mileage engine or should i replace the head gasket anyhow
|
ive heard that the stock head gasket can handle about 45psi..im sure someone else will chime in soon and say they are running 55 psi with stock head bolts. and i would just go ahead and replace the gasket on a high mileage engine. knock out 2 birds with one stone

I've hit over 50 a few times and no probs yet though but now that I said that it'll be coming soon.

Chiming in! :D
I'm peaking at 57PSI, and I KNOW I am on borrowed time. Head gaskets can go at anytime, regardless of boost. As for a time to change them, I would say 40psi and play it safe. You can change them out one at a time without any negative side effects. |
okay thanks for the help, i am glad that i can change the head bolts with out having to pull the head to put a head gasket on :yeah:

My dads 99 will pull 60lbs. Stock bolts and gasket. He did lube and retorque the factory bolts. His truck 450k+ miles now. Had the same setup since 100k. I will say though, he doesnt beat on the truck all the time, doesnt tow heavy alot, never races and never pulled a sled. He just plays with it now and then. I cant see that much boost being sustainable for any amount of time. I would bet hes never held the boost that high for even 7 or 8 seconds at a time.

play it safe and keep it under 40 unless you got a way to get home
