Btw, are the diameters for the seals pretty much the same, or will it vary by motor? I tried looking them up on Summit and they have several different diameters for an SBC. The reason I am concerned is that this engine is a crate engine, so I am not sure if it would be the same as the one for a stock motor in a '77 Chevy.
First, some clarification.

The compressor in the quote is an air
compressor, not a spring compressor, which is still needed (a spring compressor, that is).
I am thinking you will have the small O-rings that seal the retainer to the valve stem. This set up uses a tin oil shield under the retainer.
I found a page here
that shows the same spring compressor I have used successfully on stock SBC springs a number of times. It's inexpensive as well. The seals, retainers, locks, oil shields and O-rings shown there are what you will have- I think.
If you have 'positive' seals that are pressed onto the OD of the guide boss, they do come in several different ID and OD. But see what you have (small O-ring or positive type) and we can go from there.
