C6 engine mount height

Installing headers and thinking the engine height could be better? 15 yr old mounts may be squished a bit? Anyone know the factory installed height at the mount? All the aftermarket webs just say factory replacement which does not help!
Thanks for any info or advice

The factory mounts are fluid-filled;
generally if they are not leaking, they are fine.

However at 15 years, and if you have thr headers off the car; I would replace them. Both of my mounts leaked at the 13 year mark and about 90k miles.

Oem are junk and will leak over time.
Spend a few more $$ and get the urethane mounts from Hinson.

All c5 and c6 are 3". Stock. Don't know why u have 2 1/2. Maybe they are collapsed. All after mounts are 3" or they make and short version to lower the engine. I just changed mine. Just went through what ur going through. This is my experience if u find different info disregard my info. GL
