Overlap is where both Exhaust and Inlet valves on the same cylinder are open at the same time. This happens at around Top Dead Center as the Inlet needs to be open as soon as the piston starts to go down the bore while the Exhaust needed to stay open until the piston had stopped rising.
excessive overlap gives a lousy idle and can cause starting problems.
Large amounts of overlap are usually associated with poorly designed cylinder heads and high revs.
Valve Lead is the amount the valve opens before the piston arrives at Top Dead Center. the valve does not open until after the piston has passed TDC.

The stroke is an upward or downward movement of a piston in a cylinder. In a petrol engine the cycle begins with the induction of a fuel mixture as the piston goes down on its first stroke. On the second stroke (up) the piston compresses the mixture in the top of the cylinder. An electric spark ignites the mixture and the gases produced force the piston down on its third power stroke. On the fourth stroke (up) the piston expels the burned gases from the cylinder into the exhaust.
