You need to give some thought to the desired outcome......before cutting.
Generally when you cut down the divider on a dual plane manifold, it adds a little top end but softens the low end.
If the engine is in a heavy car with tall gearing, it might hurt overall performance. And vice versa.

Thanks for the response, it has a butchered up LD340 on it now with pretty much the complete divider missing out of it, right down to the plenum floor and even removed under the roof towards the front, although it seems to run half OK I don't see the total fuel distribution being great.
