What is a resurfacing machine?
An ice resurfacing machine shaves the ice, removes the shavings, washes and squeegees the ice, and has enough carrying capacity to clear the ice surface in one run, making it completely smooth. Ice resurfacing machines are widely known by the brand name Zamboni.

So you can see here quite a lot of the surface. Now. It’s starting to look pretty much like a reflective mirror surface there so you can slightly see some marks still from a gasket.

When should a cylinder head be resurfaced?
Resurfacing the cylinder head restores it to its original tolerance and creates a perfect seal. In addition to resurfacing after an engine has suffered some damage, we recommend resurfacing when you’re restoring an engine and installing OEM (original equipment manufacturer) cylinders.
How many times can you resurface a cylinder head?
You can resurface once or 50 times, doesn’t matter.
What does a machine shop do to heads?
The head is set up and secured to the milling machine. The proper surface finish is milled for the head gasket to be used. (a composite for this one) You can see that this head was belt surfaced before. The head is now blown out to remove metal flake from milling and seat cutting.
Do heads always need to be resurfaced?
Cylinder heads and blocks may need to be resurfaced to restore flatness or to improve the surface finish, or milled to change the deck height for a variety of reasons. The deck surface on the head or block may need to be resurfaced if the surface isn’t smooth or flat.
How smooth does a cylinder head need to be?
Roughness Average (Ra) is the average micro-inch measurement of peak-to-valley roughness height of a flat surface. The lower the Ra number, the smoother the surface. Fel-Pro recommends a finish of 60 to 80 Ra for cast iron cylinder heads and blocks and 50 to 60 Ra for aluminum.
What does machine shop do to heads?
How many times can you resurface a head?

How do I know if I need my head resurfaced?
The only way to tell definitively whether your cylinder heads need to be resurfaced is by measuring them. The cheapest way to measure it is with a comparator gauge. This simple tool has sample patches etched into a metal plate which indicate the different surface finish ranges.
How much can you skim off a cylinder head?
In a modern engine, the tolerance of the cylinder head should be less than 10 microns (or 3 thou in old money). This fine tolerance is because the head gaskets used in modern engines are usually multi-layered steel gaskets, which are much thinner than older style head gaskets and require much greater accuracy.

The cost of head gasket repairs can run into the thousands, meaning it’s often easier and cheaper to scrap the vehicle than it is to have it repaired. The average cost of head gasket repair is around $1,000 to $2,000, but this isn’t because the parts are expensive.
What happens if a cylinder head is over skimmed?
1. If you have to lift the cylinder head for any reason the gap between the head and the block will change (head gaskets vary in thickness) this will upset valve clearance. If the head has been skimmed the head is now closer to the block and the valve clearance will be closed up, too tight.
Can you skim a cylinder head twice?
Firstly, you can only skim the head, not the head gasket. The head gasket cant push water, it’s a gasket, that’s it. If your head has been skimmed before because the car overhetaed, and it over heated again, it is quite possible that it may need skimming again.

How long does a skimmed head gasket last?
How Long Do Head Gaskets Last? Head gaskets typically last 200,000 miles, which is considered about the lifetime of most cars. That means, if you look after your car and follow the service schedule, you should never be faced with a blown head gasket.
