I'm sorry I didn't make myself clear since you have a late model roller block by all means stay with a roller cam, but instead of running a hydrualic setup go with a Mechanical/Solid roller setup. They do require higher seat pressure springs so specify that when ordering the heads. They simply out perform the other set-ups. My two cents.. Mac
