Super Jet Resurface head?

[kawa js550]

How does this head look. It has alot of tiny scratches in the metal and I'm worried that it could be a issue. Should I get it resurfaced?

You could run a steel ruler across the surface to check for trueness. Any distortion will show up as a slight air gap.

I wouldn't be too worried by micro scratches. It's serious gouges and areas of corrosion that would cause a worry.

Preparation is key. I run a gasket scraper across the sealing surface to remove the majority of old gasket and then set to work with with a razor scraper fitted with a new (quality) razor blade. A little bit of effort usually has them looking like they've just been machined.

Once the surface has been fully prepared is when you should check for distortion. However, if major and obvious distortion or other damage was obvious from the outset I wouldn't bother with the prep and just go straight to resurfacing.

I put it on a piece of granite, like someone suggested and pressed on all the corners there was no movement. Also every side looked to be touching, so it looks like it's good!

I use a piece of granite marble countertop. Lapping stone is best or the flattest surface you can find, and a sheet of 150 grit metal sandpaper to lap my heads ,exhaust manifolds ,headpipes,cylinders etc. due to excessive salt water use its necessary . It takes down all the high and low spots you can tape the corners down or use contact glue experiment with different grits of paper and carefully use circular motion and get a near perfect gasket surface perfectly flat everytime . I always use a oem head gaskets they last for a long time .
