Lowering Springs

[Steve67RS/SS]

I have just put some lowering springs on the front of my 67. It has a big block, not sure if this will help in my question.

But it is still not as low as I would like it, actually I think it's a little higher.

do you know if they tend to "settle", if so, how much driving does it usually take and how much do they tend to "settle"

Or do I cut them now?

Thanks for any info. you may have.
