I agree with both of the boys above.
A gasket never fails on it's own.
It's a uneven clamping issue, intake not machined at same angle as the heads, or the two intake faces aren't parallel end to end.
As stated above, fit the intake to bare heads and the abnormality will show up from a feeler gauge test.
