Yes, a valley pan does as you speak. They are popular on big blocks. But, I’ve never seen them made for small blocks. I’ve never seen intake gaskets that block them either. Not saying someone out there doesn’t make them. A valley pan works. But, a gasket that covers a crossover is worthless. In short time, it will rip through. I think that’s why they only make valley pans that block them. I’m not in favor of either. They both will fail in short time. Same as, blocking it with a tin can.
