It shouldn't be any big deal to pull one spring and get it tested.
Although proper coil bind and spring pressures do not mean the spring harmonics actually match your valve train.
By faith you can accept that the setup you have is OK as is.

Installing any cam, I recommend that the springs and cam come from the cam manufacturer purchased as a set. That way IF there is a problem the cam manufacturer has something to look at besides mix and match parts.

It is always better to err on the small side when chosing cam specs. You won't mind snappy throttle response and good seat of the pants feeling, but overcamming will make any driveability seem horrible.

I have seen lots of 450 hp "spec" 350s that only did 385 on the engine dyno.
