You have no way of knowing until you check the clearances.

recently done it, fairly straight forward to do. Biggest pain is unless you have a big box of shims or a well stocked dealer nearby it takes a few days to do it by the time you audit what you have got, get the parts, fit, check  and reassemble.

I had one size on back order so it took a week start to finish, but most of that was waiting time.

Mine was a routine check, I didn't check compression or have any reason to suspect a problem. I didn't have any zero clearances either.
