Here's what I do:
- Use ARP thread lube on the threads and under the washers. I used ARP bolts and washers, no lock washers. 25 ft-lb.
- Put all the bolts in and torque them as tight as I can with a knurled finger wheel (something like this) [ame="http://www.amazon.com/SK-8-Inch-Professional-Thumbwheel-Ratchet/dp/B0002NYCWC"]SK 45172 3/8-Inch Drive 1-1/2-Inch Professional Thumbwheel Ratchet - Socket Wrenches - Amazon.com@@AMEPARAM@@http://ecx.images-amazon.com/images/I/51XQ71CWECL.@@AMEPARAM@@51XQ71CWECL[/ame]
- Torque in sequence bringing them up to maybe 15 or 18 ft-lb. Start with a couple I can get a torque wrench on and eyeball the travel of the wrench (for example, 180 degrees)
- On the ones I can't get a torque wrench on, use whatever wrench works (for me a box wrench) and swing the wrench the same amount of travel.
- Go back in sequence and tighten up again to 25 ft-lb.
- Check torque after a heat cycle, and again after a week or so. I found that with the hard Cometic gaskets I used I needed very little retorque.
