Maybe, but I wouldn't trust any thing bought today to be good enough without verifying the pressures and coil bind heights, but that is me
I have had a good valve spring checker for the last 20 yrs and use it on every motor I build to check every valve spring for its application, especially on race motors with solid roller cams.
Far better to know than to hope and find out later they weren't good enough to use on that cam and motor
God luck either way
