Since there is a need for springs that work. Decided to start a list
Anyone can add there working combo.
Crane 99838-16 install at 1.55" with 99936-8 retainers. Note. Seats and guides need cut for larger diameter springs. Use .530 viton seals. Can use +.050 or minus -.050 keepers for proper installed height. Good for .540" lift. 151# at 1.55"
Use Crane catologue for complete specs.

I will be installing some 990s in my 2R SVO over the winter. I need to replace the valve seals so I'm going to put the springs in too. It has a Crane 194621 (A-234 cam) in it now.
