Ok well, im changing the headgasket on my ED block/EF head right.
Its a bit premature, but what can ya do about bad advice.
Anyways, im planning on using an AU head gasket and AU bolts to replace this gasket with. Just got a few questions:
1) Does the AU head gasket go onto the ED blocks. Are they identical in design to the ED gaskets, bar the material used to make it?
2) What torque will i need to do the bolts too? I have read somewhere that the AU bolts arent TTY, so i was wondering will this incur a different installation procedure in the way of torquesettings, etc?
3) What overall benefits would i receive from using the AU gasket and bolts?
Never really compared the two gaskets, I'd suggest placing one on top of the other just to be safe, I reckon all of the coolant & oil holes would correspond. AU head bolts aren't TTY, tension is 30nM + 120 deg. The benefit of using this gasket is the coolant circulating won't eventually wash the gasket away like it does on E series falcons.

AU steel gasket bolts straight on the ED Block, mine is a 7/94 ED and it has an EF head(last of the ED, it has alot of EF part numbers).
I used ED/F headbolts when i put mine on.
Its been doen for nearly 18 months and had no drama's.
The AU gasket is thinner aswell, .025", so it will increase you compression ratio very slightly.
Yeah mines also a ED block with EF head...
Im unsure of the benefit of the AU head bolts, so i at this point i may still stick with ea-ed bolts, unless there is a better alternative.
In regard to the head gaasket, i think the AU one is the go so far.
Im just searching for whats best really, without spending too much more cash.
You will want the AU headbolts absolutely as they have longer threads therefore don't have issues when being tightened. I still reackon the EA monotorque headgasket is the way to go, it might wear out sooner(10+ years by which time you probably won't have the car) but it will seal a lot better then the AU metal gasket.
I used Astra (or similar spelling) head bolts on mine and on the box they say EA-AU. They have a much larger bolt head but still fit and so thats what I would use. Cost Around $30 I think. If you do a search for the thread I had on my head gasket fixing then all the prices are there.
And the torque specs should be on the packet for the gasket kit. Because different thickness and material gaskets should have different specs I'd imagine to get different levels of gasket compression. If its not printed on the packet then go to Ford and ask. They shouldn't steer you wrong.
Good luck..
