Just thought I would post a pic of a project I have been collaborating on with Kevin Fontenot. I'm design, and he is manufacture. There is really little justification to this other than to see if we could do it. It has been a lot of fun, certainly some grief, and a hell of a learning exercise.

Re: AMC cylinder head project
Does it have two spark plug holes are or those head bolt holes and if those are head bolts holes how do you put a nut on them and tighten them(the holes on the exhaust side)But now the old AMC will have a canted valve head for some.

Re: AMC cylinder head project
Man those look good! 
Looks like a spark plug hole and 2 bolt holes per cyl/exh port to me. Spark plug being on the left of the port and the other 2 being the bolt holes. You can see that on each alternating port from left to right, one of the bosses/holes around the port(right side) is close to the port, then flattens out onto the flange, and the next port it's closer to the port, then back on the flange again.

Re: AMC cylinder head project
Here is a picture of the deck side, and you can see the head bolt pattern better.
Good catch on the head bolts - that was a huge design problem. The stock head is siamese port, and obviously the bolt pattern is designed for that. The change to symmetrical was a big issue on the exhaust side as 3 of the 4 bolts I had to clear are in a different place relative to the bore - nothing symmetric at all. This is my solution - take the exhaust ports over the top of those 2. You have to use studs, reduced hex nuts, and Snap On torque adapter FRDH181 to bolt it up. The other choice was put a big angle on the exhaust port and bend it around the worst of the bolts which is the end bolt and right under the port. I like this better; a straight out exhaust port.
