got any head bolts you can part with?

We use the ajusa bold for years with turbo and blower setups. Never fail, rock solid and if you tight it up right, the are perfect.
I rebuild every year lots of stock engine's, and special projects. There not one sign tht the bold are weak or bad. 100% first hand.

What torque values do you use?

[Ron]

If you are using factory head gaskets use factory torque specs. Otherwise, the procedure/torque may be different, so call the vendor (E.G., I've used several of DPI's and they were one pass, no re-torque. No problems!)

20 nm first
60 nm wait 30 min
All back to 20 nm
And turn it 115%
Ready

Double check with ED, but I think he meant:
20 nm first
60 nm wait 30 min
One at a time, back to 20 nm
And turn it 115° (not "%")
Ready

(Like the Manual)

===========

Since I'm on a roll, FWIW-
An ISO 8.8 and a SAE Grade 5 ( Not 8 ) are almost equal (120,350 v/s 120,000 psi).
An ISO 10.9 and a SAE Grade 8 are almost equal (150,850 v/s 150,000 psi).
The difference is: 150,850 - 120,350 = 30,500 psi, or 30,500/1250,350 * 100 = 20.2%

I used the AJUSA bolts on a stock motor using Reinz head gaskets. No problems after about 2500 miles. I used factory specs.

Good news, I have the reinz head gaskets too. I went ahead and ordered some head bolts from volvo. Looks like I have a set of Ajusa if anyone needs them.

Yep, I went ahead and ordered them.

Cool! (I'm glad Giamanut bird-dogged the universal (aka "comfortable") solution ;-)

[Parzival]

Scratch that, the volvo site emailed me to say they don't actually have the bolts.

Have you called DMCMW?
