Bore for large cylinders, Cylinder seat cleanup cut or adjust for deck height:

When the case is bored for larger cylinders, the process is performed in two steps for better fitment of the cylinders into the case.

Thread repair:

For performance engines, the five longer 8 mm studs are removed and Heli-Coiled for added strength.
