Review on Dorman 674 522 Exhaust Manifold Kit by Sean Sitton

I really liked this kit. Perfect fit at both ends. Great design with gaps between the screw heads to allow for bending so the problem doesn't reoccur, which is typical of the GM 5.3. Will buy this kit again if I need to do the passenger side. Many previous users have said that the head gasket shown in the picture is not included, but it is. Inside the main box is another cardboard insert. The seal is sandwiched between the liner and the outer box so it cannot be damaged. I still ordered the OEM gasket but contrary to what many have said it is there.
