Can someone please show me in pics or describe where the low side valve for an AC recharge is on an ls1 motor ASAP please? Thanks a ton. I see a valve on the evaporator and one near the radiator. I don't know which one is low side or if it is neither.

You cannot accurately charge a A/C system only by monitoring low side pressure. It is best to charge with the proper weight of freon, but you can get pretty damn close if you monitor the low and high sides pressures.
Also just because your A/C isnt working good now, it doesnt necessarily mean it needs to be recharged. By monitoring high and low side pressures you can diagnoise many other possible problems as well.
The smaller port is the low side(suction side) and the larger port is the high side(pressure side).
Not trying to sound like an ***, just trying to inform.
