Sounds decent.
Are you planning on doing anything with the heads other than the valve springs?

In another thread I suggested having the top of the valve guides cut for positive type stem seals and port/bowl clean-up. That's a good start.
Pinning the rocker studs or having screw-in studs installed wouldn't be a bad idea, either.

Re: L98 Build list
I have been talking to the guy that did a lot of LS1 work for me. I am going to just take the heads to him and figure out what they need from there. I was thinking since they will be out there anyways might as well do it right.
