Cams, springs, and retainers

[02S281]

Getting CMS 2.5 blower cams. I was wondering if its necessary to get new springs and retainers? What are the stock ones good until?

Here are the cam specs:
.536/.540 lift, 228/235 .050 duration, 114 LSA

Thanks.

I would def get new springs, but the retainers should be okay.

So now im trying to figure out whats absolutely necessary to have. Thanks man.

I would get the springs and retainers, they are a must my book when changing cams. I wouldnt skimp on the retainers either. Look at it this way...the springs will be off anyways so you just as well put them in but each to his own.

Stock ones are good for under .550 lift, but I would do them anyways, you dont want to let a valve go and screw up your whole upper assembly.

It's a bit of a pain but take your time and it's not too bad.

I would even offer to come help install them if need be, I did mine and helped Mike with his.

Retainers are fine to re-use
