What pressure to torque used ARP Bolts?

[Cedrock15]

Hey im about to put my head back in my car and wanted to know to torque some used arp bolts i got to (used 2000 miles by another member) Its going to be used on a stock head gasket, stock turbo. I was going to to to 85 lbs but wanted to know whats best for used bolts. Thanks,

Here's the torque spec for the bolts...note the value (circled in red) for use on aluminum heads (like the 7M). Chase the bolt holes prior to installing the HG & ARP bolts. Since you're using a stock HG, do a re-torque after 2-3 heat cycles.

Consider using a spray sealer like Brake Quiet on the stock HG...a lot of guys have had good success, but the TRSM does not recommend use of a sealer either way. BTW, this is the only case where I'll say a sealer is ok...for a new MHG, you don't want to use a sealer.

Don't forget to use RTV on the front plate where it meets the head per the TRSM; otherwise you will induce an oil leak.

i'll be using oil, so i guess 110 lbs even though theyre used.?

I'd order moly from ARP and torque to 75 ft/lbs since we have aluminum heads.

Hey i got head in and went to put in my arp head bolts....nope. The side of the bolts would rub against the wall before i could get a chance to use a socket. Its as if the head of the bolt is too wide, anyone else have problems with this? if so how did you get around? As of now i just reused my stock head studs.

I use ARP Stud and the nut used to hold down the head fit almost just right for the hole. The 14 socket I use just make it in but it would be wise to lube with oil for easier drop in and removing it once u torque it. I almost panicked when I first drop it in as I had some difficulty putting in the socket 14 then I just lube it with oil and line it up straight and it drop in with some twisting around to lube it.
