Available for both small and big block Chevy cylinder heads, the small block case will house all standard small block Chevy heads and the big block case will house everything up to Merlin heads. Durable hard plastic features 360° handles for easy carrying and moving, even strong enough to be used for shipping. Built-in recesses allow for multiple stacking for convenience.
