arp headstud install
I'm about to boost my LS motor and as a preventitive measure i bought some arp's.
Now, i just replaced my headgasket a month ago. So, i don't want to have to replace my HG again if the following or similar is a proven method to install the studs with out having to replace the HG.
Can i just take out all of the stock head bolts and then install the arp's, simple as that?(of course careful not to shift the head)
Can i take out one head bolt at a time and install the arp's to the first torque spec, then once all of the arp's are in, finish the torquing process?
Or has anyone tried these or other methods to installing new head studs?

Re: arp headstud install
u cant shift the head if u dont lift it because of the dowel pins
the head does raise a tad when u losen all the bolts and sometimes the gasket ***** up
i say boost what u got now and if it leaks replace everything all together

Re: arp headstud install
once the hg is 'untorqued' and then retorqued, whether you lift the head or not, it's the same as taking the head off basically. not to mention, you have to hand tighten the arp's down before putting the nuts on and torquing them, it will prolly be kind of hard to fit your hand in the head bolt holes if you try to leave the head on :P like already mentioned, i would run it as is and if your hg blows, then replace it and the arp's at the same time.

I have done the ghetto ARP install method on a few DSM's and its always worked. Basically you take ONE bolt out at a time (in torque sequence) and replace ONE stud at a time. My old car's still on the stock HG and 30+ lbs of boost
