Magnum reseal questions?..

Highly recommend unbolting exhaust manifolds if you can rather than trying to pull it with them still on. It's a bear to get to those flange bolts.

My transmission was rebuilt 6 months before I bought the truck. Those two exhaust bolts on each side look like they've been replaced they're not rusty like the manifold to block bolts are..?..
