I have finished the installed spring height measurements, using a telescoping gauge, also known as a snap gauge.  Did each measurement four times and took an average.  Working with the two piece keepers plus getting the gauge just right is something else.  Surely there is a better way.  If roller rockers, aluminum 4v intakes, aluminum timing covers, and maybe heads can be produced, one of you guys needs to make a neat micrometer gauge like the SBC guys have to use. 

What are some common variances in final adjusted spring heights.  Given shims only come in .060 and .030, exact final figures seem difficult.  I did see that JM has a keeper that is +.050, so that would help on 4 of the springs, but dont know if it will fit stock springs.  Tried calling him this PM but he was out.
