 The stock springs are fine for a road car using C, D, E or 107 cams.  I've been running .388" lift cams for years in both 2.0 & 2.2 configurations without complications.  104 cams are a different story.

Valve float can become a problem at higher RPMs, but the 'E' and 107 cams aren't exactly high RPM cams anyway so it's somewhat of a moot point.  Alternatively, if you are blueprinting an engine for maximum efficiency & power, by all means the 16 spring rates need to be consistant!
