Just the part of the head that touches the gasket, we usually sand them on a flat surface so we can tell they're flat and not cast poorly.

Doesn't take much a few swipes and you'll be able to tell if it's flat, I've had one that rocked on the sand paper before I sanded. That's a bad casting.
Now I get it. Thank you. john

Not trying to hijack this post, Just wanted to show @Chainlube something

I wish resurfacing my Whizzer heads was that easy There's alot of surface to sand on a Whizzer head
As you can see I shave em down to increase the compression

That extra S/P hole is for a compression release button. That was used on the Ambassador, It has a starter
For my NE 5 I just plug one of the holes with a bolt, NE5 has a compression release lever on the valve cover
Or for that extra hole I could get a duel coil and use 2 S/P

That Ambassador head is nicknamed the Block Head because it's thick and has short cooling fins

If you're trying to mill it down, yes, then that is a lot of sanding. If you're checking for square, it's still a couple swipes. I bet it didn't need any.

Just a quick follow up question. The nuts on the head studs just had 1 lock washer under each nut. Is that ok?
I see some stud kits also have flat washers as well. What is best as far as head washers or does it matter? Thanks John

To shave - I use a bench top belt sander then finish on plate glass
Too bad the Belt sander can't get em perfectly flat. I gotta do that by hand
Resurfacing a head that's been used for about 1K miles takes about 1/2 hr
Rub Rub Rub, good thing I've had alot of practice rubbing one out :ROFLMAO:
