OK I've searched with no answers ARP

I had to pull my head because of some bad vavles, so i just got the head back from dad, and now i need to think of something for head bolts. Now i have searched and searched, but if i go the ARP route, are they easy to install?? Or should i just go with honda OE. I just cant figure it out. All i need to now is how to install them, and how difficult it is. Or should i go back to Factory? Thanks.
no offense but honda horns tend to sound pretty gay. so gay it starts to become cool again.

Re: OK I've searched with no answers ARP

i'd def go ARP. if you are gonna replace them the ARP head studs are much stronger and better quality than OE and the design of a stud rather than the stock bolts is that the stud is acutally pulling the head down on the block to ensure a much better seal. here is some info:

Obtaining the optimum cylinder head-to-block sealing is especially critical in small displacement engines employing high compression pistons or power adders like turbochargers, nitrous oxide and superchargers. That's why ARP head studs are popular among leading Sport Compact/Import racers.

You should know that ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Then, each stud is precisely heat-treated to 200,000 psi. Following heattreat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It's important to note that lesser quality studs are not even centerless ground the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned something that won't happen with inferior quality head studs.

ARP studs are thread rolled after heat-treat, which gives them about 1000% (that's ten times) better fatigue strength than those studs that are threaded prior to heat-treat.

You will also note that ARP offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the "stretch" of both studs, which makes for a more consistent clamping force one that compensates for head gasket compression when the head is installed. This helps prevent blown head gaskets, and assures optimum sealing!

now as for the install:

First and foremost, make SURE that the holes are clean and clear of debri. The best way to do this is to spray brake cleaner
or intake/carb cleaner down the holes, and use compressed air to blow out the cleaner and debri. Make sure to cover up the cylinders so that crap doesn't get into them though. Make sure to lube up both sides of the studs w/ ARP moly lube (which is included with their bolts), or with 30w oil (Not 10w30, but solid 30w), if you bought them used. Tighten the ARP head studs all the way down with an allen wrench, then back them off about a 1/4 turn (ARP recommends they are hand tight, and this is equivalent). But, beware. When they say handtight, they do not mean tighten them down with your hand. This is just silly because you can't thread the studs all the way down by hand; they won't all be even. What they mean is, thread the studs all the way to the bottom, but do not have the bolts applying any pressure to the block (no torque). You can also use the double nut technique, which is just putting two nuts on the stud, and using a socket or box wrench to tighten the upper nut. This will turn the stud because the lower nut will hold the upper nut in place. This will ensure that they are all at equal height. Do NOT torque the studs INTO the block. This will negate the whole reason you are using studs instead of bolts in the first place. The advantage of studs is this...the block will be "pulling" down on the head, which is the opposite force of combustion, as opposed to the head "pulling" up on the block, in the same direction as combustion, which is what the stock head bolts do. The studs help create a better seal.

hope this helps....
