It has a headEr for sure its 4 2 1 style and it doesn't leak. It has 210075 miles and I will be rebuilding it either this week or next week then plan on driving it for the break in to insure proper procedure. Hit me up for more details. Oh and as some already know I just got back from Florida. I drove the car with said engine and had no problems what so ever. No burnt oil no smoke no issues.
