Remember the late 90's vortec motors has one sender for the computer, another for the dash gauge.

The temp sender uses the ground of the sender to relay the signal back to the gauge/computer. Make sure you have a good engine ground, and i'd suggest you insert it dry into the head,,, i try to resist the temptation to use teflon tape and such that can be detremental to the ground. Brass fittings do a really great job at sealing without any tape / sealing compounds.
