anyone running ej20g heads with a 257 block? what kind of CR are you guys getting? my motor is already put together but i am worried about the CR being a tad to high? :(

Ej20G heads have a 57cc head volume. You will have a compression ratio in the mid to low 7's with those heads. They have more volume than any other EJ series head...
