Idle with crower 403's?

[boosted k20]

hey whats up. i was thinking about getting a set of crower 62402 stage I cams for my 97 LS, but now im rethinking it. i think i might go for the crower 62403 to get some more power to eventually hit 14 sec's. i will have to get upgraded valve springs too.
my question is will the idle with these cams be really rough or somewhat like stock? i heard the crower 62404 idle is pretty rough, so im just wondering how the idle is with the 403's?

with these cams and valve springs along with skunk2 cam gears and my mods below, i should be hitting 14's with no problem right?
sometime next year i'll get a set of type R pistons and put em in my block so 14's shouldnt be a problem
