Reply to "Mysterious ‘China-wall’ gap"

milling of the cylinder head deck sealing surface does not alter the china wall gap

the intake faces of the heads remain at the same angle, in the same plane and at the same distance apart from each other. am i seeing things or is the intake face of the alloy head 'proud' of the break point of the china wall and the deck surface, intruding into the intake manifolds' space?

glad to hear you were able to come up with a solution
