I might be putting 1.7 Roller rockers in and according to my calculations if the 97 LT1 cam is the same as the 96 LT1 cam then the lift settings would be .504/.521 lift. Now I think the LT4 spring lift goes up to .525 lift.

Will these work or do I have to drop a butt load of money on other springs.

Should work. Like you said, the hotcam is .525 and the springs are made for that.
