I have Edelbrock aluminum heads & manifold on my 351W and use the Edelbrock gasket #7220.  No matter who makes these gaskets, the intake gasket should fit into a slot on the head gaskets that will hold them in place.  Edelbrock recommends the use of their "Gasgacinch" on the cylinder head flange and the cylinder side of the gasket.  I've have no issues when I used this, and no issues when I didn't use it.  I always apply a little (less than 1/16") silicone around each intake port and the water passages.
I usually check the torque an hour or so after the final pass.  I have found the manifold bolts were "loose' after running the engine for a period time, but have not had issues with any leakage, or gasket moving in the long term as you indicate.

You gave me gave me an idea. I'll put torque seal on it. It's a thick paint used to tell if the bolts are backing out.

It's good to live near Summit to go pick up the parts needed to put it back together but it doesn't matter if you forget to get some of the parts you need. I need a way to get rid of my forgetter.

I'm thinking that you loosen each bolt individually one at a time and re torque it or do you just torque it from where it is? I've gone over and retorqued it from where it is about 10 times now and have even got it together good enough to run yet. All the bolts are torqued except #2 and #10. It seems like they are backing out.

Have you installed lighter advance springs inSIDE the distrib and altered the curve?!
