See link to Oatley, that's what I used, Teflon paste is ok too, important issue is the pressure it can handle. I would leave a thin layer over the grooves, it needs to compress against the head gasket. When you rebuild or do any repair on the valves, you always make sure there is no oil on the stem or guide wall. If you do, once you start the engine and the valve works up and down, the oil will dry out leaving a residue that can stick the valve. Just make sure the stem is free of any rust. Something most machinist and back yard mechanics don't do is clean the cylinders with soap and water to remove the hone grit from the hone grooves, solvent alone won't do it. If you don't remove it, rings will wear against the grit and the engine won't last as long. Depending on the time of year, slight rust may appear on the cylinder walls from washing, but nothing to worry about, winter is best time to do this as water evaporation is slow. Most people use assembly lube when assembling the engine, I use a 50% mixture of 30WAE engine oil and STP mixed together. Lube the oil ring on the piston and leave the compression rings dry, any oil or grease on them can cause them to stick.
