If they are just standard bolts, then get a length and thread type/pitch, and go to your local bolt shop.

Bolt shops sell high tensile bolts. Did you tension the bolts? I've put many truck engines together using standard high-tensile bolts that are tensioned to the correct torque, and no loctite, and haven't had any trouble.

these are a strange tension 20nm plus 73 deg.
The head has a big do on them not a grade.

Nothing strange about an angle torque. It's really up to you, if you wanna pay $5 bucks a bolt, do it, but I would be quite confident using a set of bolts from a bolt shop. If they are A/F, they would most likely be grade 8, if metric, grade 10.8

I'm fairly confident they're not just a standard high tensile bolt. I know my flywheel -> crank bolts weren't. Whereabouts do you live? See if you can get someone to set you up with an ARP retailer.

If not, $5 a bolt isn't so bad. At least holden can still get them for you, Holden couldn't source ANY flywheel bolts for me

What's so special about these bolts?

I'm in bowen north QLD
Whats so special, well if i use the wrong ones i will have some major repairs to do in a year or 2.
I just remember from talking to reps over the years that there are different types of high tensile bolts.
Some do not strecth so can be done up tight and others have a high shear strength.

So you realy need to know the spec of the bolts to make sure you have the right ones.

Which is what I have been saying all along. Find the grade, thread type and pitch, and get them from a bolt shop if you don't want to pay $5 a bolt. Holden aren't the only place to sell high tensile bolts!

The bolts have a (d) marked on the head, nothing else.
I don't know what grade d is, if you do please tell me.
