Progress I'd get a new metal valley pan gasket & mock it up with the paper side gaskets on both sides & see if the ports/bolt holes line up. A member here "topside" iirc sells .015" thin paper gaskets for cheap & I use Permatex spray gasket cement #99MA "high tack" the red stuff on those gaskets. If using no paper gaskets then I use a LIGHT/EVEN coat of Permatex #1 around each of the 8 port openings in the valley pan on both sides. People have installed em dry/as is with no paper or cement & had no vacuum leaks (requires flat/parallel mating surfaces. Holler how it runs as you continue tuning
