a 2x4 setup question

Got home late last night from a weekend vacation to find the new manifold had arrived. Looks to be at least 2" shorter then the original and this morning I got up early tinder if it would fit. I'm happy to say it has the identical footprint of the base and it actually had gaskets and bolts come with it. Tonight I will bolt everything together and start working on some linkage. I will need to make a base pivot stand but I should have everything else. Pics will be coming later tonight! I'm also thinking about powder coating both top and bottom so the aluminum matches? What are your thoughts on doing that? Again, thanks to yellow rose for this idea. I would have never thought to use a SB Chevy top!
