Cylinder Head Resurfacing Tips: How To Produce An Ideal Surface Finish

Dress and true the wheel

Always dress and true the resurfacer wheel face to keep it in proper
grinding condition. Never dress or true a wheel above the wheel center
line. In addition, always dress or true the wheel as close as possible
to the point of actual grinding. Since the grinding wheel usually wears
most often on the edges, start truing at the center of the wheel face
to prevent excessive penetration and consequent damage to the diamond
tool. Diamond tool holders and mechanical wheel dressers should be
clamped securely to the table and well supported to eliminate
vibration, which could cause knicks on the grinding wheel. In precision
grinding, the better the truing or the dressing, the better the finish
will be.

Use the proper wheel speed

Wheel speed can affect the wheel and surface finish of the workpiece. To obtain a good finish, use light cuts and a slow table traverse; both
in wheel truing and in the final grinding operation.

Use grinding fluid

Grinding fluid is important for good grinding operation. Use a generous
flow of fluid at the point of contact between wheel and workpiece.
Always turn on the fluid flow and start work rotation before starting
to grind. Keep fluid clean! Dirty grinding fluid is the enemy of good
workpiece finishing. To prevent cracks in hardened steel, use a free
cutting grinding wheel with a generous flow of fluid.

It’s not just the port work alone that creates spectacular cylinder head performance.

Your bowl area, the valve job, the throat diameter, and combustion chamber are all crucial parts. 

Tight Tolerances and Building Power

As you ascend Mt. Everest, you reach an area called the death zone. Once you climb high enough, the margin of error becomes perilously thin. That death zone also applies to engines. As the horsepower per cubic inch and rpm increase, the margin of error decreases.
