What do you guys with double valve springs do to break in a cam. I've heard you should take out the inner spring until you break in the cam and then put the inner spring back in . I'am using the crane 10308 double valve springs. It's for an Lt1 with a hydralic roller. Any advice would be great. Thanks

 

Break in a roller cam? To the best of my knowledge, roller cams are plug and play. Enjoy....

 

hydraulic cams are plug and play...

no break in needed. But i was easy on my for 10 miles just to make sure everythign felt right
