Headstuds question...
What was the highest psi you guys ran before putting headstuds? Right now I'm boosting 22 psi on stock block and stock turbo (with intake,tbe,walbro,flash tune) but want to boost higher if it brings gains...would i see increases if I just added headstuds and turned the boost up? Just want to know if headstuds would be a good choice at this point besides the reason of "extra insurance".
basically, what would be the highest safest boost on stock block, stock turbo, and stock injectors and adding headstuds
All input is appreciated, and yes I did search and it didnt help in this case.

you are playing a game of russian roulette with your motor. If you turn the boost up past the stock level, why not just replace the studs to be safe? They cost what, 120 on lancershop on sale, you can find them for cheaper some places. Ask yourself now 120 now or 10 times that later? Are you okay at 24 psi, probably, 28 maybe, 30 you should put it high on your list.
I don't mean to offend, but you know what headlift is, you know the general number is right around 30 for needing them, so why take the chance? You are fine at 22, any more, why not save yourself the trouble down the line?

Like I mentioned, I'm running E-85 (more forgiving as far as knock) and I monitor/re-tune the car regularly.

^ I agree. On average about 40% of the people that do 1x1 method have problems with a bad seal.
Those for it claim it must have been a procedural error. Those against it say do it right are don't do it at all. Some even say the standard ARP's aren't any better than the stock hardware.
Personally... I really don't see how 30psi could lift a head without detonation.

well i ordered the headstuds from maperformance so im waiting for them in the mail. i just keep hearing of ppl getting headlift 24-25, and some say they are ok at 30-31 which is a huge difference so it raised some questions to me.
and about installation im not gonna do it, but ill ask whoever will be what their method is because it does seem like its half and half on the 1x1 or remove the head

I was asking the same question and after through some informative posts decided not to get the headstuds. If you change them then you need to replace the headgasket the 1x1 method is not the correct way. It truely depends on your goal... the only time I would do it if I were building my motor.
As many people have already stated, it's too much timing or not enough octane (which causes detonation) will most likely cause the head to lift. High PSI doesn't lift heads. If you make more power (~600 + torque) than the stock block can handle, then you'll probably fold a rod before lifting the head.
