A pressure differential valve apparatus that includes a valve, the valve having a valve head and a valve stem connected perpendicular to the valve head, the valve head having a valve face with an opening that continues inside an interior of the valve head to an intersection with the valve stem and along a length of the valve stem to a top of the valve stem, wherein the apparatus allows unobstructed pressure readings when the valve face is rotated in a radial direction within an area of flow of a cylinder head.

What is claimed is: 1. A pressure differential valve apparatus comprising:a valve, the valve including a valve stem having a first end and a second end and a valve head connected to the first end of the valve stem, the valve head and valve stem having a central longitudinal axis therethough, the valve head having a valve face with an opening spaced from the longitudinal axis that continues inside an interior of the valve head to an intersection with the valve stem and along a length of the valve stem to the second end of the valve stem,wherein the valve face opening rotates about the longitudinal axis when the valve stem is rotated about the longitudinal axis, andwherein the apparatus is adapted to allow pressure readings when the valve is rotated within an area of flow of a cylinder head.
