Help! Need valve shim dimensions!

[altered7151]

I was going to run by summit on my lunchbreak to get some shims for my valve springs, and I forgot the stock one at home for dimensions. Can someone give me the dimensions on the shim, just the od and id woudl be great. Thanks!

1" ID and 1.4" OD (1.01" X 1.38" actual measured). If you're doing the conical springs, they need to be 0.030" if you have fairly fresh valves and seats, more if the valves have sunk into the heads somewhat.
