One thing to note is that LS1 valves are lighter than LT1 valves.

stock springs are only good for stock cams and usually just barely. I wouldn't run anything bigger than a hotcam with 1:5 rockers on those springs SO as long as you want to change them use a good spring and run any cam you want.

BTW here are the ls1 cam specs.
`98-`00... 198/209 .500/.500 on a 119.5 LSA
`01-`04... 196/207 .467/.479 on a 116 LSA
