sounds a littel gimmicky  ... i've run my K heads for 8 or 9 years on PULP and all good so far..
has anyone with an 18R actually had valve seat recession from lack of lube (not from hammering them)???
the main valve seats that have problems are those in cast iron heads, as they often do not have a seat insert, and the cast iron is what wears away. the hardened toyota seats should be ok.
also fwiw, 'lead free' petrol (or lead replacement) still DOES have metal in it.. i believe it's manganese and maybe another one (according to Shell australia) so there is still some valve cushioning effect, and is not suitable for cars with cats or O2 sensors...
Cya, Stewart
