Hey guys getting ready to install and break in my Lunati Voodoo 268 hydraulic tappet cam and just wanted y'alls opinions on my springs to make sure their not too stiff. I'd hate to wear down a lobe or lifter on break in Thanks for your time and help guys.

Spring pressure closed 115 lbs @ 1.800

Spring pressure open** 310 lbs @ 1.225

Coil bind is 1.130

Install height is 1.800

Max valve lift is .575

And here are the cam specs
