All machined surfaces performed CNC, including bolt holes, to achieve extreme accuracy in finish.  OEM bolt holes for compatibility and these heads are T6, Heat Treated.

It is necessary for you to dis-assemble these cylinder heads and clean them before installing.  This ensures that you will not have abrasive material from the manufacturing contaminants inserted into your engine.
