Re: Preliminary checks when swwpping used LS

Look at ALL of the exhaust manifold to head bolts. Notorious for braking off the end bolts. Remove the manifolds, weld nuts onto the broken studs and unthread while still warm from welding. The stock bolts are lock tighted and the welding softens it for a while. Nice to do this with the engine out of the vehicle.
