Default Do I need new spring shims with crane duals?

It seems like the stock shim will not sit in the inner spring correctly.

TIA!

I thought the Crane valve spring kits always came with retainers and hardened seats? Mine did.

It sounds like you didnt change the seats and the seals. You can't use the stock ones. Those aren't shims. The shims are used to get your installed heights to yeild the seat pressure you want. If you're running high 220 ish .570ish cams and need say 124lbs seat pressure you need a .030 shim for an installed height of 1.77.

Went up to barnett, picked them up and installed them. I ended up getting everything from barnett and when you order via the part #s from crane. The valve seats or retainers don't come with the springs. Car idled fine for the 15 mins or so that I let it run. Going for a drive today.
