Factory. Of course that's pathetic because it's factory and factory engineers are usually morons.
OEM 412 RC12LYC Champions for Gen I and II Vipers were gapped at .035"

I'll probably be trying out the 438's found on the Gen 3. Do you know if the gap is the same?
2006 Service Manual: 438 RC12ECC with gap 0.033 to 0.038
