Default Choices for valve springs

I got a 351 stroked to 427. Im using brodix 505 heads and I want to go with a comp cam with a 565 lift. What would be a good valve spring to use?

232/[email protected] and .565" in and .574"ex on a 112 lobe sep. Comp spring for that cam is a 986-16 or the premium spring is a 26986-16

986= 132#@1.750 inch and 293#@1.250inch coil bind is 1.150 inch and the dual spring is 1.430" diameter. Something with same characteristics and a little larger diameter spring will do well for you too.
