i just did my coolant pressure test and i don't have any leaks does this mean that my manifold gasket would not do it job properly?

Cooling system pressure test will not show up internal head cracks, this must be done on the bench by a head machinist with special testing equipment, also heads must be checked for warp and bend as well.
