I don't want to steal this thread but I have a question.
I am in the beginning stages of a 408 build. I have contacted Campbell, AD Perf. and Hughes about the rotating assembly. I wanted to use flat top pistons with the RPM heads, but I was told that it wasn't a good idea to use flat top with the build and these heads because the CR would be around 11.5-1 and that was real close to the limit on these heads. They all advised staying with dish pistons. True/ False?
