Those are not the .675" lift EHT springs...they are a standard .650" lift spring.

Well, after running around the horn 3 or 4 times today, I discovered that this is actually a Patriot Spring Kit that's on my heads... Found out because of the valve locks that you have to get specifically from Patriot.
