Question

Quizplus · Accepted Answer

When selecting a cylinder head for an engine with an aluminum block, it is best to use an aluminum cylinder head. This is because aluminum and cast iron have different expansion rates, and if a cast iron cylinder head were used, it could potentially warp or crack due to the heat generated by the engine. Using an aluminum cylinder head allows for better compatibility with the aluminum block and minimizes the risk of structural damage.
