Head Bolts
The Magnum uses different head bolts than the LA engine — all of the long bolts on a Magnum are the same length. Additionally, some of the Magnum engines used Torque To Yield bolts, and as such are not reusable. Fortunately, ARP makes stronger-than-stock head bolts for Magnum engines.

Torque to yield bolts ARE REUSABLE.

We don't have the proper equipment in our home garages to do "torque to yield". It's expensive.


However, they have to have a "service" or "repair" spec. It will usually fall in the range of 45 foot pounds + 90° turn. This is acceptable for a factory or home repair also.


You shouldn't use a torque to yield bolt more than 5 times as it will eventually get overstretched and then break.
