Final answer:

Positive type valve stem seals must be installed before the valves are installed in the cylinder head.

Step-by-step explanation:

Tech A is correct. Positive type valve stem seals should be installed before the valves are installed in the cylinder head. These seals help prevent oil from leaking past the valve stems into the combustion chamber.

Tech B is incorrect. Valve stem seals should not be pushed down firmly over the top of the valve guides. Doing so can prevent the valve from moving freely and cause other issues.

So, the correct answer is Tech A.
