I finally got my 496 onto the dyno. Break in went great! sounded good no leaks(other than junk valve covers) all ok...Go to do first pull on engine. Its making good power for a first pull and all of a sudden we hear a noise and power dropped off. Pulled the valve covers off and found 3 rockers seized to the shaft. Also bent three valves. Great....

I am now hearing that Comp changed the design of these rockers? I bought these in 2006. Is there a better rocker to use? The car has a solid roller in it. Going to be a street/strip car.

Thanks in Advance, I'm going to call comp and see what they say...
