Cylinder head

I'm guessing I would start from the inside and work my way out. Combustion chamber first. Then squish band. Then mating surface

It's easy to sand, so don't hurry.

Finally installed the new head. Here is a pic of the inside of the old head and one of the new head on the bike.

A rotary tool and scotch brite bits followed up with polishing pads and compounds. Then a bit of patience and willingness to get dirty lol.

I used these specific ones as they go up to "1000" grit. I then did 3 stages of polishing compound with cotton buffer pads.

Turned out looking ok.


I then did as previously described by doing the flange surface on a piece of glass with increasing grits of sand paper. I only did up to 400 grit, which is more than enough. You can keep going up in grit if so desired. I recommend doing this part last if you use a rotary tool, as you can see evidence in the previous photo of me having a few disagreements with the flange surface and the buffing wheels more than a few times.

Damn! That’s clean…
