I finally found some time to take a look at the PAC Racing valve spring. Its not identical to the Crane spring, but yeah its close.

I have one concern with that spring, at PAC's rated 1.88" installed height the spring has only 98 pounds seated force. If you install the spring at the standard Cleveland height (1.82") the seated force is great (120 lbs) but the maximum lift is reduced to 0.540".

If it were me I would juggle the installed height to give me just enough maximum lift for the cam lobes & rocker arms you are using, while maximizing seated force as well.
