I wouldn't even consider installing a comp spring on my car. I've seen waaaaaaay too many cases of them breaking.

With that being said... I'm running LS6 springs.

xp cam here as well. and that website has no relation to the 3800 market. the gt cam on website is in reference to an LSx cam.

and there is a lot of talk about the LS6 springs being harder on the valvetrain and wearing out the dampener quicker than the alternative 105# springs. can't comment on that as I have yet to pop off my front cover since installing them.

The crow cams springs are a reliable spring. I would suggest going with at least 105#s if not the 130#s if using the CC XP cam.

what about these lingenfelter springs 1998gpgt is recommending. I preferably dont want to use comp cam springs cause those didnt last to long.
