99+ had the heads EH'd on both ports.
98/98.5 only had a single pass on the secondary port.
99+ had the larger LIM. (RLIM)
The UIM itself was revised in 2000. "Technically" the 2000 SVT has a unique UIM.
We won't get into other part revisions done for late 99 or 00. Too many to list. This was just an E0 vs E1 thread afterall.
BTW I love my E3 SVT.
