Are you going to run stock exhaust manifolds? I'm not sure what aluminum heads you have there, but somewhere on FABO another member had to grind some material off of the driver side head to get the manifold to fit. I hope you don't have problems with that. You may want to mock it up to see if it clears. Please let us know how it works out. I'm interested in running aluminum heads when I get there. Also, let us know which heads you have there. Thanks.
