Engine Mounts for 180hp C172M

Has anyone had experience of the differences between Lord and Barry
engine mounts - particularly in a C172M with a 180hp conversion?
I am in the process of having my engine reconditioned and I will
replace the engine mounts.
For all the time I have owned the aircraft (C172M with Avcon 180hp
conversion), the engine vibrations have cracked the cowl fasteners
(the actual metal supports which are riveted to the firewall).
The cowl mounts are the Skybolt SK series.

Now I wonder if the engine mount type will make a difference to how
much vibration is transferred to the fuselage. Currently the aircraft
has Barry mounts.

Any ideas?

Thanks
Robin
