IMO, this is why flywheel housings crack so readily.

Just want to clarify, you're saying that the housings crack more readily with the stock mounts or the FAMs?
FWIW, I converted to FAMs earlier this year and retained the stock front mount. The vibration reduction was noticeable and clutch chatter is not an issue. I used the transmission mount that was included.
There is a great write up from MikeK somewhere explaining how the vibrations of even a mildly hopped up engine, like mine with a 5.5 head and reground cam, produce a ton more vibration than the stock engine and that the FAMs really do help to alleviate that BUT the rubbers need to be soft for them to do the job.
