25ftlbs is too much. It will distort the top face of the block and cause problems. If both surfaces are flat, a torque of 18ftlbs is enough to seal the joint. If it won’t, the real answer is to fix what’s wrong, not wind the head studs up further.
One thing that’s often forgotten is there is a leak path up through the thread of the stud. You need to apply thread sealant to the stud before it’s wound in to the block.
