G`day ,

you may want to have a look at the ARP site and the updated December 2016 figures they now give . You still decide on what to use though .

I`ve used helicoil type for head bolts before and would be my preference because they can be fitted to the height wanted and the breaking of pins it .

I see they are now stating 70 ft lbs !! I guess I was lucky to get to 100 safely

A few weeks ago I did 75 pounds using ARP lube into my 4.6 P38A block and it felt good and felt right. Cheers

I use Permatex Aviation Formagasket on the actual gasket for the water pump. Just a bit of added protection. Use sparingly. Cheers

would much rather use 100 than 70!!!!

Can I still use ARP studs with a helicoil?

Don't see why not. I reckon stress on threaded hole of any sort has to be less than that applied by a torque to yield bolt...

Just make sure it's well bedded in and full length.

Cheers

Can I buy and install myself?
