I am going to install a Mech Temp Gauge on my 94 Z/28 and i would like to know the best place without taking my stock gauge lose to hook up a new gauge on the engine block, Like where to find a water jacket on the block. Thanks

 

There is a mirror image plug in the RH head, but it is hard to get to and get out. It takes a 5/16" square drive to get it out. You could alway get some fittings and plumb a "Y" into the one on the driver side head or water pump or plumb one into one of the heater hoses.
