head or valvecover??

i have been dismantaling 2-95 formulaIII,s to do pistons
on the one i ride. other sled is a parts doner with a
destroyed crank & 1 bad jug & piston.
my question is- on the sled i ride the temp guage
sensor is in the head. on parts sled its in valve
cover??
the parts sled doesnt even have a hole for the
sender in head. so what place is better??
the head on sled i ride has a plug in the v-cover???
funny thing is the vin numbers are only 53 apart
so what changed ??????

Go to www.hlsm.com and check the microfiche for different years. Maybe they will show both.

Not sure. My 617's all have the hole in the head (top cover), not the cylinder.

Wonder if it's been apart and they tried to change the compression ratio or something?
