There is a artical in Chris Endres "Chevy LS1/LS6 Performance" book on how to do that, Page #58.

You disassemble the stock Thermostat and use a 1/8" brass ferrule as a spacer on the inside of the housing, if you cut the spacer down to .090 thickness, it will open at about 168 deg.

Here is a scanned page. Sorry about it not being better, but this should point you into looking for a copy of the book and what page to read.

You can switch to a housing that uses a standard GM thermostat.
It's made by CSR, part number 911LS1.

while it helps to reprogam the fan settings, when the car is moving your temps will stay low, regardless of the settings.

i drove my car for several years on stock settings with the 160 stat and still saw benefits.

fans will help when sitting in the staging lanes, but a simple fan switch will do the same thing.
and if your sitting in rush hour traffic...who needs the added power from a cooler engine? as long as the car doesn't over heat due to some other issue...stock settings will keep it safe in traffic.

side note...watching the scanner my 160 stat keeps temps right around 175* when moving.
