two, one in each thermostat housing
Okay, they don't actually call them "poppet valves" -- the thermostat is held down by a spring. when pressure gets high enough it lifts the 'stat off its seat.
Call it a "high-pressure bypass" or a "pressure relief" if you will.
Same function.

The best way to answer your question is to buy a clymer manual for that engine. If I remember right they are at the bottom of the cylinder heads. It has been a while but I dont think they are even by the thermostats, it doesnt make sense since they are put in to even out temperatures throughout the cylinder heads.
