Adjustable fracturing head and manifold system

A system comprising:

• a fracturing manifold;
• and
• a fracturing tree coupled to the fracturing manifold, the fracturing tree including a fracturing head to receive a fracturing fluid from the fracturing manifold and to transmit the fracturing fluid to another portion of the fracturing tree, the fracturing head comprising:
• a body having an inlet port, an outlet port, and a bore to enable the fracturing fluid to flow between the inlet port and the outlet port, wherein the body is an adjustable body that permits movement of a first portion of the body having the inlet port with respect to a second portion of the body having the outlet port to enable variation in a dimension of the adjustable body and to facilitate connection of the fracturing manifold to the fracturing tree.
