Magnum reseal questions?..

It's basically all the same as an LA. DON'T pull the cam or distributor. That will mess up the sync with the PCM and it will need a special scanner to sync it.

Side note, my grandpa has a '96 1500 with a 5.9. It has 473k miles on it. The engine has had valve seals replaced while in the truck, and the plenum gasket replaced. They really are great engines.
