All cylinder head stages include something that no other head
manufacturer uses: RA Finishing of the head mating surface. This is a
finishing process that ensures the optimal finish for proper sealing of
the head gasket. Simply machining the head perfectly flat is not
enough. A mirror-like finish is not optimal to proper head gasket
sealing. The RA finish puts the right amount of grit onto the surface
of the initially machined head, helping it most optimally “bite” into
the head gasket when the heads are torqued down to proper
specification. This process has been proven by many OEM and performance
builders to provide the best sealing possible. Chrysler vehicles, that
were notorious for head gasket sealing issues, fixed their already
problematic design by factory RA finishing of the heads. Combining this
technology with the superior head design of the VQ35DE, allows for the
best possible mating of the heads and the block of any internal
combustion engine.
