The following sequence of photos show some of the repairs that were needed following the separation of the seized heads. Two of the stud bosses were damaged, and the surface of both blocks also required weld repairs and surfacing. Thankfully the bulk of these major repairs are now behind us and we can press on with with the engine rebuild.

This Flat-12 Ferrari engine came to us with both cylinder heads seized solid. Using traditional extraction methods and a custom fabricated pulling plate, were able to separate the heads from the block just enough to allow us to cut away the cylinder head studs - allowing us to remove both heads.
Our next task is to drill out what remains of the cylinder head studs.
