are the OEM ones from Honda just as good for running some boost through a B-Series without having the head lift?

arp's are cheaper and better for boost than oem.

if you haven't pulled the head off the block and running stock internals; stock are fine. if you've removed the stock head bolts, you don't want to re-use them and arp would be what you want to get. higher boost over the stock mapsensor limits, i would recommend arp regardless.

arps or golden egle with the dog point legs. once a bolt has been torqued it has been twisted and streched already. too many times = broke bolts. now studs hold in a compressed manor so theres greater force on the head without super high torque specs. i torque around 75-80 depending if nos is being used as well. some times people use a small shot to spool these big ass bastards lol.

75-80 seems high, arp specs 70 and thats what i torque to, 800+ hp no problem.

Get some headstuds and be done with it. Stock bolts are just crappy as hell...ARP or golden eagle ones will get the job done, Ive used both and they are both great.

yeah maybe a little high, i usually go by the specs by golden eagle like 30ftlbs then 50 the back off and retorque to 50 3 times to seat the studs then go to 73 ftlbs. and it has never failed. any ways that waht my instructiones said and its workin so far.

i always pull to 30 and then pull to 70. Re-torque after the first dyno tune.

Do not Use the ARP Fasteners, USE the Golden Eagle ones.. Much Better stuff

ive only used ARP studs and torque to 70 ft-lbs (because i used the supplied moly lube). Never had any problems.

Factory bolt are torque-to yield meaning the stretch. Ive never boosted anything that had stock bolts but im sure there are ppl that have. Id just put on a new headgasket and studs from the get go so u dnt have to question it later.

and what experience do you have in this? Ive used them all and they are BOTH rated for the same clamping force. 800+ and not a single blip on the temp gauge and never a blown head gasket.

Most failures are from improper Torque, torque pattern, or a problem elsewhere causing failure such as bad sleeve, or warped deck. All of the studs are prime products. we're talking about 220,000 psi of clamping force, the marginal differences between the brands is not enough to matter for something that doesn't have slinging forces being put upon it.

well said! yeah theres some out there claiming 10 seconds on ticking time bomb crap that say there using stock bolts. but there the dumbasses that dump ass loads of money into a 10 sec, hulled car and motor then for some ungodly reason go with stock bolts,humph wierd. i think ill stick with 220,000 tensil strength and wait on thiers to go boom while were still making passes.and i honestly dont think there making 800+ on stock bolts,lol. if your gonna improve upon the stock format then why not improve it all and leave nothing to chance on stuff made for run around 200 max hp?

lol because 200 hp is my target amount of power :D

spend the 100$ and get studs, you'll thank us later when you do some maintenance or something happens and you have to remove the head, bolts are always a bitch to take off...and they can twist and strip or twist and screw up the threads, not torque right...its just bad news.

The head studs are good, but the engine bolts themselves aren't worth the money.
That's what I've heard, anyway.

Alright, but they're like a one-time use type of thing right? Like, i buy the head-studs, torque them down, and then if i need to pull them off again i cant use them again after that? :???: or is that just how the stock bolts are?

My memory isn't exactly fresh at the moment since it's floating in alcohol.

EDIT: It depends, so don't go by the number of times being used. Basically, if it's feeling tight/secure during torque down, it's safe to use, and as long as it doesn't take more than the normal required torque to install them.

As it was said earlier, they aren't crazy expensive. If feel unsafe in reusing them, just get another set.

thats just stock bolts...
