So I tore into the car today - didn't get too far before I had to quit this evening.
I started my Valve Spring swap today - I got one cylinder done - and have many more to go.
I ended up using the cheaper LS Valve spring tool off ebay - link below:

Quality seems decent - and I'll be able to get the rest of the springs swapped with no issue.
I am upgrading to Comp Cams 26918's since my CNC ported L92's have L76/Truck valve springs on them - and I don't want to see any valve float when I throw some boost at them.
