Upgrading Rockers, help! spring advice...
http://www.summitracing.com/parts/na...5494/overview/
The 'baby' beehives work too; just know that they've got about 15% more seat pressure than the LT4 valve springs (105 lbs vs 90 lbs - if I recall correctly) at their installed height (Again, if I recall correctly 1.800") and they require different retainers and keepers / locks than stock.
Additionally, if you decide to go with the LT4 springs, then the retainers are known to be the next weakest point in the system. I found this out the hard way when one of my GM LT4 retainers failed - I did a Google search and found out I was not the only person who experienced LT4 Hot cam kit retainer failure. I now use Comp Cams stuff - I've had no issues, but I've read that others have not been so fortunate.
Good luck - Have fun!
