When I was a youngster, I used to skim my motorcycle cylinder heads this way. I always used old mirror glass , and valve grinding paste instead of sand paper. It took ages, but it always worked.
pro tip use sanding paper for deck resurfaceing sander there massive and solid and come with doublesided tape on it home depo sells sheets in rental section
wellllll… depends.On my 1996 camry, 500grit was what was required to meet spec, so I was golden (did it in a parking lot)… But it should be mentioned that Some of these new MLS gaskets require a surface roughness (Ra) equivalent to damn near mirror. High compression, and all that jazz.

This works great. The Head gasket will take any thousands of differences.

Good job? This way still works to 4 cylinders head, heavy one? and how about the surface of engine block?
I picked this video cause that looks like a subie head.
For 120.00 bucks my machine shop man will have a perfect surface on my cyl head in a jiffy.
Right! Good to know people!
320 on Subaru.
But after rectifying the surface, how do I calculate the measurement of gasket cylinder? or just put the same measure?
I use a new oem spec gasket. Unless there is damage to head you should not have to resurface much to get a clean gasket surface.
@@peak_ascendr9960 thanks dude
Thats a good idea
I prefer to keep to the sandpaper dry and after a few days I Vacuum the dust off the sandpaper.
Did you use stock head gasket or steel ones
I can't get my fire ring to disappear lol....I just can't bring myself to mount the heads with it still being visible even tho I can't feel it lol
I have a vq35de aluminum heads and engine block any one know what sand paper grit I should use for the final pass I’m using the oem gaskets
If the OEM head gaskets are composite then 320 grit should be fine. If they're MLS then 400 to 500 grit for the finishing touch.
What grit was used ?
0:24
Why they don't have larger sandpaper ?
Works the spray alright and can you take 'IT' of after ?
Skateboard griptape
how did it hold up? Doing it to my EJ25 right now
What sand paper did you use, ill be doing this soon since there are no machine shops near me
If head is heavy just block sand it
