A heater head assembly for a multi-cylinder heat engine the stirling engine, such as a multi-cylinder Stirling engine, having a plurality of regenerators and cylinders. Each regenerator has a regenerator manifold and each cylinder has a cylinder manifold. First identical cast heater tubes connect the regenerator manifold to first heater tube openings in a heater head manifold. Second identical cast heater tubes connect second heater tube openings in the heater head manifold to the cylinder manifold. The first and second heater tubes are parallel with respect to each other and form a pair of partial concentric staggered arrays. The heater tubes are rotationally asymmetric, having fin sections with less surface area upstream than downstream and thicknesses which decrease radially away from the central passageways of said heater tubes.

[ What is claimed is:] [1.]1. A heater head assembly for a multi-cylinder heat engine, having at least two essentially discrete volumes of working gas, said heater head assembly comprising:a plurality of regenerators, each having a regenerator manifold,a plurality of cylinders fluidly coupled to said plurality of regenerators, each of said cylinders having a cylinder manifold,a heater head manifold, having a plurality of heater tube openings, comprising first heater tube openings and second heater tube openings, and passageways between said first heater tube openings and said second heater tube openings, anda plurality of heater tubes, comprising first heater tubes and second heater tubes, each of said first heater tubes extending between one of said regenerator manifolds and one of said first heater tube openings and each of said second heater tubes extending between one of said cylinder manifolds and one of said second heater tube openings, thereby allowing said working gas to be shuttled between said regenerator manifolds and said cylinder manifolds through said first heater tubes, said heater head manifold and said second heater tubes and allowing said working gas to absorb heat.
