I think with more aggresive cams it could be beneficial......not sure when just adding NSHC's like I did.

Put it back together with the shims that came out of it and see where you're at then adjust from there.
I think there is a fairly std size from the factory but not sure what it is/was.

The stock shims are around 280-290 on the intake and 315 on the exhaust from what I've seen. Can't speak for ferreas but my kibblewhites were fairly close. I didn't have to change intake shims at all and just had to drop the exhaust shims by a few sizes.
