Re: ls/vtec head studs
Correct. If you were using a B16 head on a LS/VTEC, you'd still use the GSR Head Studs.
The difference is the length. The deck height on an LS/GSR is higher than the B16, and the threads are deeper in the block because of it. Really and truly, it's a matter of choose your favorite manufacturer. Although, reading as to how the threads are done on certain ones, how a stud is supposed to work, versus others, I have my preference.
Head studs are studs for the head. Main studs are studs for the main girdles on the crank.

Not starting a flame war, I'm interested. I've had success with AEBS, thats why I prefer them.
OP. Use a factory headgasket. I know several over 500 all the way up to 700 on factory gaskets.

And since you actually do know what you are talking about, please post up which ones you prefer.

The threads are cut different on the Golden Eagle.
Theoretically, it has stronger threads.
The added size of the AEBS makes no difference, as the weak point on any stud/bolt is the threads. Legends motors have a shaft of one size, with threads that appear much larger, because of this. (Saves weight/cost in manufacturing) As for the bottoming out, both use a dog point on the bottom to ensure full thread contact. You only install studs hand tight to begin with. I just happen to like the thread cut on the Golden Eagle studs a little better than some of the others. Do a little reasearch on SRT-4 engines, and you'll see an example of the cut pattern used, and what it does.

AEBS looks to be good.

Re: ls/vtec head studs
To be honest about it, unless you're looking to go 500+ whp, (probably a lot more) it won't make much difference. All of them are very good, and cylinder pressures aren't really that high as to break threads. Hardware wise, I'm not sure about which ones have a greater footprint on the head, but....

Re: ls/vtec head studs
Both AEBS and Golden Eagle told me to torque them to 10ft/lbs. I know that isn't that much more than hand tight. But figured it was worth a mention. You just want to be careful that you don't put the tip of the stud through the bottom of the hole in the block. which can happen pretty easily.
Or the nuts holding the head?
