edelbrook heads

My son and I are putting Eddy heads on the 400 we will be putting in his Dart to replace the 383. If you have the flattop pistons set to zero deck and use the felpro .039 head gasget it should come out around 9.5 comp with the 84 cc heads and then you can mill the heads a little to get the comp where you want it and have a good quench motor. So with flattops I would use the 84 cc heads. Ron
