Well, I drove my truck for 9 months Z'd and stock motor mounts. I had no issues at all. Probably put about 40k on it that way.
The only minute issue i had was a slight vibration during driving very very low at high speeds. It was a non issue for me really, i drive slow, and at normal ride height, because our roads are awfull.
I lowered the motor mounts, and the vibration went away.
i think you will be fine.
