Valve spring pressure when valve closed?

Guest

Hi Jack,

Just got my heads back from a valve job.
The heads were sent in because of stuck valves. (car was in storage for 2+ years).

All was cleaned up, and looked like new. Several new valves. Noticed some spring shims as well. Used old springs, but the old setup only had 2500 miles on it.

Noticed that I was able to "rotate" several
of the valve springs by hand, with the head off the car. I thought that when a valve was at rest (closed) that there was to be some pressure on that valve. In other words, shouldn't the spring still be somewhat compressed? And being so, Should I be able to rotate the spring by hand? Note that they were not loose, but could still be turned with moderate hand pressure.

Please advise.

Thank you,

Tom
