Smarty Jr shift points & valve spring ?'s

[EArp]

Got the Jr last Thursday and let me just say WOW!! The power is unreal. I've had several WOT runs on the performance setting and I happened to notice on one of them that it shifted about 3-400 rpms past the redline. I also noticed while revving the motor while in neutral that the revlimiter is apparently disengaged because if I just goose it the rpm's will go over the redline. I guess i'm just a little concerned because i'm not sure what the stock valve springs will handle. I'm sure it's nothing to worry too much about, but just thought i'd ask. After all, it's never past the redline but just for a couple of seconds. Anyone know what the limits are on the stock valve springs are or have any feedback on this topic?
