That method is ok... but you might want to loosen the front and rear mount through bolts and see if the engine "settles".
For me... I get minimal NVH as long as the rear mount through bolt is at the top of the mount tube. If I start getting some decent NVH, I loosen the rear bolt and the rear of the engine usually drops... or else I have to pry it back down. I'm not sure if this is "normal", but this is how my car is. The minimal NVH is felt through the steering wheel... nothing rattles from it.
My front mount is solid 94a as well... so is it possible that untouched front mounts, or ES inserts don't balance out the resistence? I thought I read here, years ago, that if the rear mount is filled then the front should be too, or the front mount might get trashed.
