Which coil spacers to use

[SMoon67]

I need to raise the front end of my 67 small block about an inch (measuring at the wheel opening at it's highest point).  I'm guessing 5/8 or 3/4 inch spacers would accomplish that.  I know a 1 inch spacer will net more than a 1 inch rise.  I'd appreciate some comments from those who have done this.  Open to suggestions.  Thanks.
