I'm running a 2004 LS1 with an A&A Supercharger. Other then the supercharger, everything else is stock. I'm having an issue with possible valve float above 5,500 rpm's. It has been suggested that I change the valve springs to get rid of the problem. Question, beehive or dual springs, and who's to use? Has anyone else run into a similar issue? If so, how was it fixed? Thanks......
