Hmmm, my 00' had seperate seals, never seen the one piece seal/seat before. Anyway, like metioned above, you can use a socket to install them which is what I did. I just pushed them on by hand using the socket, you can actually feel them seat that way.

The ones you pulled off look like this:
These were introduced in 02 and combined the seal and the seat. With the Crane retainers, you need to revert back to the older style seal that doens't have the seat integral with the seal (umbrella type of seal). The retainer goes on first, then the seal.
Caution caution caution.
If you are shimming the springs, and don't install them and set up the springs prior to installing the seal, you may end up replacing seals again. You need to do all your installed height measurements, etc. to figure out the required shims and then installed the shims/seats and re-measure to ensure it is correct. Once you have everything figured out, then install the shims against the head, then the seat, then the seal and finally the springs, retainers and locks.

I would check with others who are successfully using that cam, and ask them about their spring setup as far as installed height and what springs. This will help determine how much seat and open pressure you need and from there the installed height requirements.
What rockers are you running?

EDIT*
Yes the 832's need shimming. Ive always recommended the 833's and used them. Sorry about the confusion.
