Or just the gasket Lee.

Often people port both the head and the inlet to match the gasket, as no pont having the two match and then the gakset being different.

Usual way is to align the gasket over the manifold and give it a quick light spray of black paint, then remove all the painted bits, same for the head.


Varies from car to car though of course, not always a good idea to go as big as the inlet gasket.
