Here’s a Nissan SR20DET cylinder head we did a complete three angle valve job & surface to. The valve guides were worn out of spec so we installed some new guides before machining the valve seats on the seat-and-guide machine. We then surfaced the deck square & flat with the proper RA for an MLS head gasket.
