Default For those who use ARP head stud

what is the torque sequence on those, acording to ARP it just said 85ftlb that it but acording to Subaru:
1. 22ftlb,
2. 51ftlb,
3. backoff 180 degree,
4. bolt (a)(b) 25 ftlb
5. (c)(d)(e)(f) 11 ftlb
6. tighten all bolt by 80-90 degree

should i just do 85ftlb??? or should i go with 85ftlb and tighten all bolt by 80-90 degree more?
the reason i ask is because i blow head gasget 3 time already with in 1 month by doing just 85ftlb.

85 ft lbs sounds really high. Was that just their generic spec? I am sure it would just fine threading into a cast iron block.

my opinion would be to just follow the factory torquing specs. The thread pitch and bolt diameter haven't changed, so that shouldn't change the required torque. The material might have changed, but I can't see that varying too much.

The difference would be in the amount of stretch the bolt material has.

Chai, Forgive my ignorance. Two questions for you: 1. is this a dohc or sohc engine? and, 2. When did arp make head studs for a sohc? I know they are available for dohc.

Got a part #? arp web site shows them for 2.0. 2.2, and 2.5, but their all the same part #. That does'nt make sense since all the 2.0's are dohc and all the 2.2's i've seen are sohc. There is a difference in head thickness so they would have to be different lengths hense different part numbers. The last I heard was that they only had them for dohc.
