I am going to buy my rocker arms this week and I need to know what type of rocker arms to get. What are the pros and cons on certain rockers. I have a bbc 454 @ .30 over with 9 to 1 comp in my jetboat. Everyone keeps telling me to buy stainless from comp. Is it worth the $258.00 bones. I want something very reliable and good without spending over $300.00. Any info would be greately appreciated.
