McMaster-Carr carries a full range of Clover grinding compounds, in both
grease based and water based formulas. The catalog provides a little
guidance on which one to select. Lapping is a nice finishing touch, but
should not be expected to take the place of a seat and valve face
resurfacing job. see page 2014 or 2015 of catalog #100, or the website at
McMaster.com, under lapping compound. Leave the lard in the kitchen.

Most auto parts stores should have it. The most commonly available is
made by Permatex. Some older parts stores may still carry a brand called
Clover, which was extensively used in earlier days. The Permatex, if
memory serves, has a bit coarser abrasive, and cuts faster. Clover, I
think, has a less aggressive abrasive, so it's less likely to cause
trouble if one gets overly ambitious.
Cheers.
