Your cart is empty.(Vtec, B18C) Built for the Acura Integra... 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!

ARP makes quality bolts, needed these to replace the original ARP set. Yes you can reuse these but in high HP applications after a few times reusing them its also good to replace them for peace of mind which is what i did.

Had a headgasket issue due to boosting 15psi on the stock oem headstuds. Loosing coolant and coolant reservoir filled with coolant/water. Smoke was also coming out the exhaust.Installed these ARP #208-4303 headstuds on my 95 Acura Integra GSR B18C1 engine.Also installed a new headgasket and torqued everything in sequence 25ft lbs , 50ft lbs, and 80ft lbs final torque.Reassembled everything and the engine fired right up without any issues.No more loosing coolant or smoke from the tailpipe!Engine is extremely strong now and should go 10.8 - 10.9 in the 1/4 mile next time out.Thanks

Worked as advertise. No issues. Just wish there instruction to install was clearer regarding torque procedure, i.e first torque 25 ft lbs, second 50 ft lbs, and last 80 ft lbs to make clear cut

Good product! Just What you would spect from ARP.It comes with everything you need to bolt that head down. Studs and nuts.Always get the ARP torque lubricant when installing these.
