Accepted Answer
Anytime you upgrade the cam, you need to upgrade the springs.

Yes, a spring upgrade is highly recommended as the stock springs were barely adequate for the stock cam when new. Leaving the stock springs when running an aftermarket camshaft will lead to valve float and poor performance.

The TFS-2500100 is a great upgrade kit for stock heads that includes everything needed for the spring upgrade.
