Valve Spring question

[Rabbit16v@attbi.com (Rabbit16v)]

Your right, Dan, it does depend on lift but the stiffer springs will defend
against valve float (I've had it happen with stock springs) and, like I
said, seems to make a crisper feel on acceleration.  As long as you have it
apart I'd DEFINEATELY install the HD springs especially when you never know
what the future holds!  You may want to spice it up a little more!  But, if
you are feeling the financial bind then I'd do what Dan did and stick with
the old stock springs (although new stock springs may be a good idea??!).
Although I don't see where stiffer springs will increase wear and lose HP???
More on this Dan??
