What is the best method of Cylinder head resurfacing? Just like the question ask? I just want to make sure the head is good and straight.

You mean how to check for warpage? Put a good straight edge on it like a 3 ft level or metal yard stick.

I wouldn't trust any of them to have a edge accurate to thousands of an inch. You only have 0.008" to work with. They make a machinist straight edge for measuring flatness.

I meant as far as using a belt sander or a mill or other options i'm unaware of. At the machine shop.

If your machine shop uses a belt sander I suggest you grab your head, walk right back out the door and go elsewhere.

READ the thread I posted earlier. It explains everything you want to know and was written by machinists. Pay particular attention to the second post.

If it were mine I'd only work with a shop that was set up machine it in a mill and only after seeing that it needed machining. You can't replace material removed so unless it's not flat or the RA isn't correct for the gasket you don't want it cut.

I had it placed on a mill and i am not sure if it needed anything removed till in the morning when i pick it up.

The method that a machine shop uses to surface a head would ideally be dependent upon what head gasket will be used with the engine.

If you are using a Multi Layer Steel, you want the surface to have the lowest roughness possible. From my experience, the best way for a machine shop to acheive this is by using a grinder (stone) to surface the block and head.
