I honestly don't think there should be any problem at all in replacing each crankcase bolt/stud one at a time, and using stainless items to do this with. I think some people are wary of using stainless bolts because they've heard they have lower tensile strength than the original zinc plated bolts. While there may be some truth in this, in practice it is generally irrelevant because the torque settings used for crankcases are way below the limits of either stainless or HT steel of that diameter and length. In other words, if you were to tighten a crankcase bolt to say 3 times the recommencded torque a stainless one might snap whereas an original one might not. But tightening within the limits specified in the manual, no such problem will be even remotely approached. You won't overstress a 5/16" bolt at 20-odd ft/lbs whether made of stainless or not.
As for Molnar, it was his reputation that caused me to put a lot of faith in his products. However, it is obvious that a lot of what he sells is merely off the shelf stuff obtainable at lower cost from any stockist of stainless fasteners. I don't think many of his items are really made on the premises, but are simply bought in and, in a few cases, tweaked a little to make them look unique. I've just bought a set of extended front disc bolts and a rear wheel spindle nut & washer, and I'm not very impressed. The heads of the bolts are not well polished (lots of coarse marks) and the stainless Nyloc nut is just a standard product available at half the price locally, and its washer is so dull I'm going to have to polish it myself. Not what I'd call good service at his prices!
