super duty head studs

[littleredstroker]

How many psi are stock head studs good for?

 

[Diezel Dawg]

They are stock head bolts, not studs.

 

[dentexpowerstroke]

There isn't a set psi that they will pop its based on cylinder presure not boost.

 

[littleredstroker]

Bolts. My bad . I always heard people say blank is good to blank psi.

What Ken said.

And its really all in the tuning. Back in the day the quote unquote said level was usually 40psi ish.

There have been guys running more... And guys running less before a failure or not.

To be honest with the coin your shelling out, and by having to ask Im guessing your going for 450+ HP whats another 700$ for the piece of mind.

 

[littleredstroker]

I coukdnt agree more. Just building my truck one piece at a time and wondering what I need to do next..

LOL what a dyck.

I would do the head studs next and while you have the VC off go ahead and do the valve springs and if you can afford the push rods as you will have the access. Then you will know you have everything set under the VC for perf. I am sure some of the BP that turbo has created has taken what are likely now very weak stock valve springs past their limit so that is a must IMO. At least its just a small price compared to studs.

This is very true. I just recently installed studs and prior to installing, I was hitting 42 Psi on the street, no issues

How often did you do that and for how long and what turbo? Very interesting when considered in conjunction with whats being reported on a stock forged bottom end.

Not very often, but occasionally on the street, and occasionally at the track. Did this with my current setup w/GQSSB

H11s are a great investment if you are gonna put some real power down. ARP ain't bad but definitely not as well made as the h11s they're pretty much indestructible.

That's really interesting. What nozzles are you running?

 

[littleredstroker]

Ok so can you do em without pulling the heads? I've heard both ways. I want to do it right but if I don't need to pull heads I don't want ti

 

[littleredstroker]

The bolts, not springs.

 

[Big Bore]

Do not remove the heads. You can do it on the truck. You do not want to break the factory head gasket seal. Those gaskets are cured/set in place.

I have been at or near 500hp since 09. Installed the headstuds in March. I'm running 100% nozzles.

Just recently.hit 550hp
