Completely cutting ALL runner dividers IS NOT the way to correctly modify this manifold. However, some lengths could use adjustment. This is a manifold that worked really well AND it fixed the distribution issues inherent. I was only 'allowed' an evening to work on this so, it isn't 'done' ...I'd have cut away some of the clover at the flange among a few additional asthetic improvements. ( another 2-3 hours work?)
