Current Chinese EQ Heads. Ports or mounting holes in wrong location? Pics here.

IMHO

Only putting a factory OEM manifold on with gaskets and bolted down to check for alignment is a valid test.

Also as a control looking at the fit between OEM head and OEM intake with gaskets and bolted down is needed to make the claim that the head's ports are off.

OR OEM engineering documentation .

I'm not saying that the Chinese parts are right or good, just the testing needs to be more scientific in nature.
