6.2 Liter GM Gen V LT performance CNC cylinder heads (pair w/ valves)
Factory Mast performance takes the OE head casting and improves it. 
This cylinder head comes with a larger aftermarket intake valve that improves average CFM flow by 30 CFM over the standard size Factory intake valve.
We completely overhaul and deck the machined surfaces.  CNC port intake and exhaust port, with a performance valve job.  
These heads retain the factory DI port injection hole, but if you're looking to run port fuel injection, add these plugs to your package.  Direct Injection Plug Kit

NO CORE CHARGE, NO SENDING YOUR HEADS IN

Our team carefully inspects, pressure tests, machines, and qualifies our gently used factory OE heads.  We machine and qualify the deck, and all surfaces to better than factory.
