I like the color. It's different.
With that cam, a carb bigger than 650 may actually be ok. If work has been done to the heads, in addition, then bigger will probably be required to get the most out of it.
RE spacers, if you have the money, Hamburgers performance make a tapered dual plan spacer that might work well. If it is a race engine, try some of the HVH or Wilson Manifolds or similar tapered spacers. For a tighter budget, the simple open, 4-hole, and divided spacers can help a lot and you can stack them in various combinations. If you can fit it under the hood, 2" - 3" or more of spacers may help.
I've been using the starter from
