Paired gaskets

Gasket holes with reasonable alignment to the head ports, but could do with being smaller to get a greater overlap

Struts welded between flanges to stop them turning in towards the middle. Note the blow marks from the outer ports towards the middle. Note also that while an Allen bolt would be fine for the left inner lower hole (A), the right inner lower (B) is completely covered by the line of the right outer pipe (C)

Very poor alignment of manifold ports to gasket holes (bear in mind alignment of gasket holes to head is good), all have some degree of obstruction. Note signs of blowing on the outers

Outer (right-hand here) port set back from inner, however it is aligned correctly so an extra gasket should be OK
