You will have to resurface your cylinder heads from time to time to maintain peak operating performance. There are a few reasons as to why you may want to do that:

• A blown gasket. This causes a total failure of the head gasket and necessitates resurfacing.
• A corroded, pitted, or scratched cylinder head
• Installing a new aftermarket inlet manifold
• Improving the compression ratio
• You may just want a better finish

 
Cylinder head resurfacing is a delicate undertaking. It requires specialized equipment and skilled technicians. Heavy Equipment Repair Services Charleston has both. 

Why is Cylinder Head Resurfacing Required?

Smooth cylinder heads result in fewer leaks from the gaskets. The smoothness of a cylinder head is measured in RA (roughness average). This metric is set by the manufacturer and it varies from cylinder head to cylinder head.

Cylinder Head Finishing: How to Get the Perfect Finish

Cylinder head resurfacing is a delicate process. To do it right, you need proper equipment and a highly skilled operator of the said equipment.

​Heavy Equipment Repair Services Charleston has both the tools and the people skilled enough to use them.
 
Some of the things a technician needs to know include:
●     The proper feed rate
●     The proper rpm
●     The accurate combination of the table feed and rpm

Is It Possible For The Finish To Be Too Smooth?

Yes. A cylinder head can indeed be too smooth. Smoothness is measured in RA ( roughness average). The RA is a ratio of the pits and bumps on the surface to the horizontal plane.

​Owners' manuals often recommend an RA value between 30 and 60. A smaller number indicates a smoother surface compared to a larger number.
 
The exact RA value for your cylinder head is determined by your manufacturer so you should consult your owner’s manual. Too smooth and too tough are both bad as they cause leaks.
