Bbc holes are out around and upper than sbc.
My old sbc have spacer between riser and manifold. So now bbc height is right with those holes that i have, but bbc exhaust is 5cm (2") wider than sbc/side.
With sbc i have Alpha, but now i have Bravo1 with bravo exhaust y-pipe.
I have silent choice, what is best option for me?

I made these when I switched to higher exhaust, it all depends on space.

Making an offset in that short of length is going to be a challenge. I think I would fill the transom and and recut the holes. Stainless Marine manifolds might ease your pain a bit if you are set on keeping your existing exhaust exits - the risers have some side to side adjustment.
