I am trying to learn about the advantages /disadvantages of going to a hydraulic roller cam versus my flat tappet. What are the pro's and con's? I have a 440 and I want hot street but able to drive it in the country. I realize that I need new rockers/pushrods but would I need to machine my heads for springs etc? Tell me about what you have learned, please! Thanks...
