heard of this being done, mtnviper claims hes run his with slp pipes and had no problems for 3 years, some claim its not a good idea
you can run the stock viper with one gasket, use permatex coper spray, shake it for an hour before using it, spray it empty upside down and store it laying on its side or upside down.
you will need to run super after this, compresion isnt too high but squish is tight.
ran this setup for about 2500 miles, from the day it was new.

The top and bottom layers are .010" each. The middle layer is a .005" shim.
You can run both outer layers with out the center shim, -.005
Or can run one outer layer with out center shim and top or bottom layer, -.015"
I have never tried using one outer layer and the center shim, -.010. Not sure how well the shim would seal next to the cylinder/head, since it dosn't have the sealing ridges stamped into it.
Like BETHEVIPER said, use copper coat, and always run good premium fuel.

i run it with just one layer. seat of pants says it helps. throttle response is crisper.
