z16se gasket on a e/c16se

Has anyone used a z16se gasket on a c16se?

would i be right in thinking the z16 uses a steel gasket?

Id have thought they would be interchangeable but look like the holes are slightly different at the oil hole to the lifters. i dont have one side by side.

at 1 mm thinner would be worth a hp or 2 if it fitted.

They are the same iv used them before

Is the z16se head different from c16se and e16se? Or are there differences?

The combustion chamber looks different, and one hole for the idiotic egr.
