Can't you just use an XCAL to do that instead?

It worked in my Subaru. I can't think of anyone who's tried it on a SHO, but I've heard it works for quite a few cars.

They use them with some success on the Gen Coupes.

I once had a 96 Taurus SLO with two inefficient but not clogged cats. I used two 18mm spark plug non-foulers found at napa and drilled the one closest to my sensor and P0420 and P0430 were no longer a problem...
