Quote: I orderd the valley pan w/o the hole, but recieved with it. It was mislabled at the factory, so I cut a soda can with a pair of scissors, making 4 plugs to sandwich them on each side of the pan. I held them together with RTV and sealed the perimiters.....works great!
I used a alum soda can,it burnt thru in short order. way to thin. may have better results with 2 stacked like that.
cut some from the old vally pan and rtv them in place on the head, then the install the gasket/pan/gasket/intake.
