Springs ok to use ?
I have purchased the BTR stage 2 cam but and wondering about the springs to use.
I have laying about home an unopened box of comp double valve springs #26926
Outside Diameter (Outer): 1.320"
Inside Diameter (Outer): .920"
Inside Diameter (Inner): .654"
Seat Load: 129 @ 1.835"
Open Load: 470 @ 1.160"
Coil Bind: 1.100"
Spring Rate (lbs/inch): 505
Max Lift: .675"
Will these springs be fine to use for the BTR stage 2 cam ?
(227/234 , .614/.574, 113+2)

Not with stock rockers - too much open spring pressure. The BTR website, regarding that cam, indicates: "Lift approaching .650" or more while using stock 15 degree rocker arms with too much open spring pressure can damage valve tips long term. We recommend maximum lift of .630" and maximum open pressure of 400 lbs when using stock rocker arms."
