Cylinder Head torquing specs.....

[Sprmcy]

This is the second time I'm using the same ARP head bolts. How many Lbs would be recommended to torque the heads. I'm using 1.2mm HKS MHG.

Go to ARP's website and look up the torque specs. The torque specs vary depending on the type of thread lube used.

use the original (ARP) specs. Clean the threads and lube as per ARP. They are not torque to yield bolts, and assuming they weren't preloaded into the plastic range the first time, they can be used again.

use the original specs.

You don't mean the original Toyota torque figure, do you ?
That was only 54lb/ft, which was the whole problem with the 7m prematurely popping head gaskets.
The widely accepted figure is 75 lb/ft with stock bolts,
some even go to 85 lb/ft with aftermarket fasteners.
But don't try that with stock bolts, as that (85lb/ft) is where they start to strech.

No, he means the original ARP specs.

I think that's what I said in the second post.

It was then echo'd by the third post.

And the 5th post has done the work for you.

I think we're all on track here!

no I don't, though I see how my post was confusing. It is now edited.
