wondering wat valve springs can i run with my cc306 i dont want to do any head work just switch the springs out i know i can use the 918's but is their anything else out their more bang for my buck?

 

Beehives (918s) with 1.6rr would work.1218s are good too. You could also use EX-612s from combination motorsports if they still make them ... rated at .006 cc306 with 1.6 rockers would rate at .544/.576. What made you decide to use cc306? Your gonna need a good tune and supporting mods to use it to its full potential. Not to mention I doubt you would pass emission test if your state has one. Have you consider a hot cam kit? It doesn't sound as aggressive but it makes good power too.
