Abstract
A cylinder head includes a cam holder mating surface and a cylinder mating surface. The cam holder mating surface is non-parallel with respect to the cylinder mating surface. Ignition plug holes are formed in the cylinder head and a cam holder. The plug holes are aligned and have a common extension axis which is perpendicular to the cylinder mating surface and non-perpendicular to the cam holder mating surface. A bolt attaches the cam holder to the cylinder head and extends in a direction which parallels the extension axis of the plug holes, is perpendicular to the cylinder mating surface, and non-perpendicular to the cam holder mating surface.

A cylinder head for an internal combustion engine comprising:
- a cylinder head body;
- a cam holder mating surface formed on one side of said cylinder head body;
- a cylinder mating surface formed on another side of said cylinder head body;
- and
- at least one threaded bolt hole formed in said cam holder mating surface and extending into said cylinder head body perpendicular to said cylinder mating surface, wherein said cam holder mating surface is inclined with respect to said cylinder mating surface.
A cylinder head for an internal combustion engine comprising:
- a cylinder head body;
- a cam holder mating surface formed on one side of said cylinder head body;
- a cylinder mating surface formed on another side of said cylinder head body;
- an ignition plug hole formed in said cylinder head body and having an axis of extension;
- and
- at least one threaded bolt hole formed in said cam holder mating surface and extending into said cylinder head body parallel to said axis of extension.
An internal combustion engine comprising:
- a cylinder head body;
- a cam holder body abutting said cylinder head body at a cam holder mating surface formed on one side of said cylinder head body;
- a cylinder mating surface formed on another side of said cylinder head body;
- a first threaded bolt hole formed in said cylinder head body;
- a second bolt hole formed in said cam holder and aligned with said first threaded bolt hole, wherein said first threaded bolt hole and said second bolt hole extend in a common direction at a right angle relative to said cylinder mating surface, wherein said common direction is non-perpendicular relative to said cam holder mating surface;
- and
- a bolt engaged within said first threaded bolt hole and said second bolt hole to attach said cam holder to said cylinder head body.
