ARP or H11?

[Amfw119]

Does it really make any difference at all?

[NSublet]

I would like to know the same thing. I know H11's can be reused over and over. What about ARP's?

[strokinpower]

I was told as long as ARP's arent over torqued in the first install then they can be reused?

Yup, I think the H11 may have a higher tensile strength, but I am not sure.

[Amfw119]

I'm going to do a little research before I buy one or the other

Do a search on this. There are tons of threads all over the internet. From what I've read, the ARP's are fine unless you're building some 50+ PSI drag truck. The block will give before the studs do either way.

I'd save the money and get the ARP's and make sure they're installed correctly.

The block will break before you stretch (properly installed) ARP studs. H11 I'm sure have a higher tensile strength but when it comes down to it who needa stud stronger then the stock block?

I would save money, go with arp unless your going to have a 1000+hp build.

ARP's are rated at 220,000 psi tensile strength. The H11's are rated at 240,000. The block of the engine will blow to pieces at 220,000

edit: lol I forgot about ARPs newer STUDS the really expensive ones, maybe someone will post a link.

thread on the new ARPs, mash here.

My only thought is, I'd rather pay a little more for some extra clamping force and hopefully make sure I never have to touch them again. I've seen 1 too many posts about having to do them again... Thoughts on that thought process???

Unless you are building some seroius drag or pulling monster, the regular ARPs will be just fine. Installed correctly of course. It is more importatnt to make sure the heads are machined well, that you use OEM gaskets,a dn torque the studs corrrectly. I don't think H-11 are worth it unless you find that you have high enough cylinder pressures to stretch the ARPS
