Yes that is next to the most accurate and most expensive way, it is also irreversible, once done, no more playing around! You must also know the compressed gasket thickness in order to get the squish right. It is because of this that saw builders normally shoot for a nominal squish of between 0.020 & 0.030 and as close to 0.020 as they can, they can get much closer to 0.020 if they eliminate the base gasket. In the case of a work saw vs. a all-out race saw a couple of thousandths makes little or no difference, only the stopwatch will notice, bad race technique will sometimes negate any advantage gained.

Paper gaskets in this country come in different thicknesses as does annealed 110 copper shim stock but you must cut your own.
