Review on Patriot Exhaust H8426 1 Length Header by Stephen Johnson
The screw hole in the head is too small for the screw.
Two questions. First, one of the two bolt holes on the seventh cylinder is too small to let the manifold bolt through. picture included. Second, not enough clearance from the #1 cylinder exhaust pipe to allow the spark plug seat to interface with the #2 cylinder spark plug. The right head had to be loosened completely to get enough clearance to slide the spark plug seat towards the cylinder get #2 spark plug. Cylinder #1 needs to be lowered about 1/4 inch to access the #2 cylinder spark plug. You don't have to remove the head to remove and install the spark plugs.
