I was looking on crowers site today, and with the 402t cams, they say they require their upgraded springs and retainers. I was wondering if I already have some skunk2 dual springs and titanium retainers, if I can still use the 402t cams or not. Thanks

 

bump for an answer.

 

I dont see why you couldnt use them...more agressive cams call for a harder spring so you dont get valve float...If im not mistaken

Call up the different companies and see the spring rates on the valve springs are and compare....
