A "valve grind kit" is a set of gaskets typically used when a head is removed to regrind the valves. It's needed on this kind of job.

Sometimes excess oil consumption can be caused by just the valve stem seals wearing out. This is a much simpler job, as the heads do not need to be removed. Unless, the piston is at BDC instead of TDC and you drop a valve into the cylinder. OOps!! (Voice of experience)
