you could go with the b303 or just run the 1.72 roller rockers on your heads and leave the stock cam alone. Using the 1.72's your lift would be .477 instead of the stock .444
I agree keep the stock cam and get a set of 1.72 rocker arms, it's not worth the time and expense to install a cam for minimal gains with stock heads. You're better off saving up and getting a cam and head combo
well along with this post, because i was thinking about getting some 1.72RR's would i need to change the valve springs or pushrods? or would the stock ones be just fine??
its usually a good idea to change the springs for a fresh set. if you are keeping the stock cam then go with stock springs. Aftermarket cam, get a spring set rated for the amount of lift you are looking at.
