The ARP bolts are stronger and get torqued to a certain spec, while the factory head bolts are torque to yield and get torqued to 22 lb/ft, then 2 passes of 90*.

aka you can torque the ARP bolts more than once

what do u mean by torque? unbolt and re bolt?

Yes, the ARP's are re-useable, while the stockers are TTY, which means torque to yield...as they're tightened the bolts stretch, and if you have to remove them, you have to chuck them.

so u recommend the ARP? are they heavy duty compared to the stockers? may stockers break or anything?

Well I'll be using stockers when I build my LQ9, there's really nothing wrong with them for most N/A applications. The ARP's are heavier duty though, which is good in a boosted application where there's a possibility of lifting a head or something. They're also good if you plan on pulling the heads more than once for whatever reason, since they're reusable unlike the stockers that must be discarded once they've been stretched. The stockers aren't prone to breaking or anything like that though...at least not that I'm aware of. I'm pretty sure that the ARP's are considerably more expensive than the stockers, but not 100% sure

I like the ARP studs myself. Never having to pull the bolts the remove the heads is awesome. Cleaning those dam bolt holes is a pain.

how many times do you plan to swap heads? The 60 dollars it is for stock TTY bolts is plenty for your build. If you plan to swap heads weekly then studs would be best. Most ppl buy set of heads once and they are done with it. So use of ARP isnt needed, but ppl do like to spend money

I think I spent like 130 on my ARPs..? 60 sounds about right for the stock bolts too...but if you pull heads even just one more time, they've almost paid themselves off.
