as far as i'm aware, they only make them for the 6.1 heads. it will bolt up to the 5.7 heads, but you will need to do some port work to match them up.
unless you are running the '09 and newer "eagle" 5.7, which has the same intake port design as the 6.1.
or you could run 6.1 heads on an older 5.7 block, but you would need to watch your compression ratio, cause it will be around 11.3.
just some thoughts
