I would imagine that this difference will cause a difference in spring pressure compared to the others. I have a mild cam so I’m looking for a 60# pressure. No access to spring tester so I may set up the bathroom scale. Just wondering if anyone has encountered this? I don’t like the fact that they are different lengths. I may have to purchase a new set or find some v8 springs with spacers. Thanks!

Do not even bother measuring those springs. They have 2 strikes against them right out of the box.
Go ahead and set up your bathroom scale on your drill press. You will need it to check the springs you finally use. 60 lb. will be fine for street use with most any cam.
Changing to V8 or any other springs can bring it's simple rewards such as dampers or it can be a nightmare having to make spring seats, regroove valves and buy different retainers. If you are not familiar with changing spring sizes, stick with stock replacements and shim them if they will go to 60. Be sure to check each spring for coil bind when installed.
