2JZ Block Machining Service for 1/2" Studs

Upgrading to 1/2" head studs?  The 2JZ block needs to be machined to accept the larger studs. The head also needs to be machined out.

If you're choosing to upgrade to a fire ring style gasket, add that machining service on here for a package price while it's in the machine.

All services are separate. The base is 1/2" block machining only.
