Head bolt install - ARP

I know the sequence of install and torque settings just a tad confused on do I just put arp ultra torque lube of washer and back of head bolt or on all the threads too?

No thread sealer? Thread lock on threads?

Thanks fellas

You put the ARP lube on the bolt threads and a little under the bolt head. No sealer or loc-tite on the bolts. Make sure to blow out all the holes in the block VERY well before installing the blots.

I was just cautious of the lube on all the threads. I didn't think any bolts went into water jackets.

No water jackets, lube them up and throw them in. You will want to put some red hi-temp RTV silicone on the intake rocker arm bolts if the heads have been ported.

When they port out the intake runners the bottom of the rocker arm bolt hole becomes exposed and oil can leak down in to the runner.

Here's a pic of my P/P 317's, see the bolt to the right of the valve...
