You cannot use the stock springs.

PSI 1511 or Manley are the only options for reliability.

Both install around 1.8 inches.
PSI install at 1.8 inches,
Manley 1.81 with no shimms needed.
I dont think the PSI would need much shimming,especially if you used the stock spring cage,and get some .03 and .06 shims and your good to go.

You wont need to measure the Manley setup.but it is crazy expensive.
Good luck with the build,it is Not a easy fix,for some extra HP up top.
