Remove one spring. measure the installed height.
Take the spring and a retainer to a automotive machine shop and get them to measure the pressure @ the installed height
and the open pressure @ full lift. Then the coil bid height.
Phone or email comp cams and tell them what you have. They will advise you.. its free too.

I would advise upgrading the spring, After having the second "as supplied" S/R torquer spring break, I installed a set of comp 981's and no more problems. This was on a XE268H cammed 350 with 1.5 rockers. As F-BIRD'88 mentioned..you need to check for any binding issues, especially with the 1.6 ratio.
